Swimmin’ With The Virtual Fishes

artificial living fish in Second Life

I came across an interesting story couple days ago over on New World Notes (a blog maintained by a Second Life-embedded reporter) about fish with artificial intelligence coded into them swimming and replicating in the simulation. I wanted to see it for myself so logged on today for a peek. Very cool. Unfortunately there were only a few fish left as apparently there was some kind of population explosion which forced the Creator’s unforgiving hand (sounds alot like a Flood story to me). No matter. It was still interesting to see them “swim” around. The pyramid object you kinda see at the bottom of the above image (hiding behind the lowest fish) is a food/sphere “dispenser” and they didn’t stray too far from that. And while they swam around me, they didn’t appear too interested.

My favorite part of the story however is actually in the comments section, where the following line sounded especially intriguing:

A virus was quickly introduced to kill off the mutant fish before they either crashed the servers or they evolved a way of teleporting to the main grid.

That’s classic. You can read the whole story and comments here.

Real Enough To Kill

Within the gaming community, news of players assaulting or even killing other online game players isn’t really new. And here is a follow-up over on the BBC News website to one story that made the rounds recently about a Chinese player so infuriated over the sale of his loaned, virtual sword that he killed another player.

Now what’s interesting to me is how the general public will shake its collective head in disbelief. Understandable. Murder for any reason doesn’t make much sense to me. But for every “crazy” it’s-only-a-game story, there are doubtlessly hundreds of equally nonsensical ones that most of us now don’t think about twice (and I suspect more and more the evening news doesn’t report about them because they’re not sufficiently sensational to keep advertisers happy). Some possible examples:

– murder over a pair of sporting tickets (just to see something you could probably watch on television for free)
– murder over some cheap family heirloom (that has no value beyond the sentimental)
– murder over drunken comments made at a bar (when words are at their cheapest)
– murder over a sporting affiliation (because not cheering for the team wearing the right uniform is simply a killing offense)
– murder due to jealousy (because when you love someone, you have to control them and sometimes kill them)
– murder over skin color (because… well, just because)
– murder over religious beliefs (…!…)

So can someone explain to me how killing someone over a virtual sword is any different than the above? I’m having a difficult time segregating.

Mercedes DCX

Biomimetics isn’t really a topic I cover here, however two other areas seem to be increasingly tied to it. The first is the RepRap project. That makes sense to me since creating objects free from manufacturing constraints allows forms and solutions more like those in nature. Hard to beat Mother Nature. I’ve always been fascinated with the internal structure of bird bones for example – they’re strong and beautiful at the same time.

The other area is industrial design. As the 3D tools used within the profession become both more powerful and increasingly user-friendly, it’s only natural that forms will become more expressive and draw from a larger pool of inspiration. Mother Nature has a big pool and is pretty inspiring.

That said, I came across a short Yahoo photo blurb earlier this evening about Mercedes’ new concept vehicle – the DCX. Okay. Pretty funky. But not enough information for me to get really interested and bookmark the link. So leave it to WorldChanging to put some meat on the story’s bones in their write up. First, they have a more informative story on the vehicle. Second, they discuss the development of the vehicle (gotta love that). And third, they have some great links, including one to the Mercedes presskit. Awesome. And from that kit I grabbed the following images:

The top image I have to post. Even a fish deserves his/her 15 minutes of fame and being the inspiration for this vehicle qualifies in my book (we could use more fish in place of some characters in the news lately, imo). The second image is near and dear to my aerospace engineering heart. The third image got my attention because it both reminds me of those bird bones I mentioned above, and because it looks like an RP model. And the fourth image needs no explanation.

Now go read the article over on WorldChanging. But take that comment regarding the shape/coefficient with a grain of salt… a big reason for high drag coefficients are the seemingly minor things: non-flush surfaces, antennas, side mirrors, aso. I don’t see alot of that on this concept. All other things being equal, a flattened wedge does have a better coefficent (profile drag is the largest component of the overall equation). However, if you go sticking a bunch of aerials on that wedge and have mismatched surfaces all over and…. well, you get the point.

Pinch Feed Me

Olliver's Pinch Feeder

Vik Olliver has posted the above image to the RepRap Project blog. Unfortunately there’s apparently no “permalink” to the specific blog entry, so I’ll just quote Vik’s description:

Adrian is currently printing the first draft of the pinch wheel feed mechanism for the extrusion head. It consists of two interlocking pinch wheels that push the 3mm Polymorph rod down a guide and into the opening in the 10mm PTFE rod… Small holes in the pinch wheels can take metal points if additional traction is required, and the symmetrical clamp should hold the PTFE rod centred.

Two Views And Mine

MIT’s Technology Review site has two interesting entries on the subject of intellectual property. Because this blog covers an intersection of sorts between virtual and real “product” from a designer’s point of view, the topic is – as stated in previous posts – of interest to me. Here’s the links to the two positions:

The People Own Ideas!” – Lawrence Lessig

The Creators Own Ideas” – Richard A. Epstein

I’ll be honest, while I appreciate Lessig’s point of view, I think Epstein is more on the mark. Thing is, free tools and cultural freedom have little to do with most of what I come across on a regular basis. Empirically speaking, there’s not really all that much “remixing” as far as I can see in the realm of 3D content; mostly I see accurate, unremixed CG versions of movie characters, props, actors and real world objects/products posted.

For example, take a look at this site, which was front page news on CGChannel recently. For all I know these CG models were created with the open source Blender 3D application, and that’d be wonderful since I very much support Blender. But I bet they didn’t use it. More important is what this person or persons is selling: virtual replicas of designs created – and in all likelihood patented – by automobile manufacturers (Mercedes, Volvo, Audi, etc). Is that wrong? Well, the people at that website (probably) didn’t design these things, yet they’re obviously hoping to make a profit by selling these designs. Shouldn’t they be creating their own designs and selling those instead? Isn’t that the kind of freedom that’s behind much of the open source movement? empowering people to do their own thing? I’d venture a significant number of people doing 3D haven’t read the memo.

Now let’s take this further: if there’s nothing wrong with this practice, why not just scan the real parts instead of laboring in some complex 3D application to recreate them? If profit is the motive – and apparently profit is involved here – then streamlining the process makes sense. Okay, then, so when people can fab their own products, you could have piracy beyond software, movies and music. People could pirate pretty much anything!

Oh wait. We already have some of that:”Yes, it’s a copy of the Honda…”[edit: the link keeps reverting to a registration site, so Google china automobile piracy and select “Piracy on parade at China car show” which is the third or fourth link down](and here’s some more here, and here).

As someone who makes a living as a designer, I can tell you that for those individuals interested in designing, fabricating and selling their own products outside of the corporate cubicle, there is a very real concern that their efforts will not be adequately rewarded. Consequently, since the effort to bring a product to market is substantial, many don’t bother. And that’s bad for everyone.

There’s an old saying that comes to mind when I read/hear people defending piracy and/or preaching the virtues of free everything : “Be careful what you wish for… you may get it.” And btw, that site I linked to above is registered to an individual in South America. Wonder if he attended that rally in Porto Alegre?

(edit: happened across some additional discussion with some interesting links on another blog here)
