Seriously. Work for an ISV (Independent Software Vendor) this summer.

Better yet, if you're really adventurous (since you're going to be 15), get an internship at CRS4 - a really neat place in Sardinia (Sardegna) about 25 miles from Cagliari. Sardegna is an incredibly beautiful place (I lived there for a few years, but up north in Sassari.)

There are probably exchange parents in the area you could stay with.

lol I've lost this post twice now. Great. Even shorter rewrite ahead!

2D collision detection is easy, and it's all that's needed here. I did 2D collision detection when I was twelve. Line detection is more complicated, but plenty of algorithms and code are available to do it - for example code, you could probably look at neon/emboss type plugins for the GIMP. Just combine the two by detecting if one line moves over an object in your scene and you have 'gesture recognition'. You'd also need to do a bit of 3D stuff when detecting how to apply an acceleration the model on-screen. Perhaps the system here recognises hand shapes as well, but again IMO that's not an insurmountable task and isn't very amazing these days, when you get mobile phones who's cameras do "face recognition".

Go look at http://www.crs4.it/vic/data/papers/ieeevr2006ws-holo.pdf and you'll see that this is not a plasma screen, it's a clever use of a large array of projectors and box with mirrors in :p All the self styled experts on /. are just slagging it off and saying the Wii guy did a better job. His method is indeed very cool, and great for a single user, especially since it only has to render a scene once, same as any current 2D computer game. The 3D projector thing will work to provide at least partial stereoscopic vision though as the display does appear to change depending on where you are standing, and not just for one person, but for anyone at any angle. It has much more potential for advancing towards true 3D display tech than a head-tracking device, and I for one think it's pretty clever and had never heard of that method before.

FWIW here is a smart approach to such opinion mining http://www.crs4.it/ict/dart06/slides/attardi.pdf

Semantic analysis of opinion in USENET http://www.crs4.it/ict/dart06/program.html and follow the pdf link under G.Attardi of Univ. of Pisa Italy "Extracting Dependency Relations for Opinion Mining" - treats languages other than English - avoids Chomsky

And the rendering below, from this very software, is of a fully naked man, penis included!

I can't believe this! This software is even capable of rendering lifelike penises, as seen by this image of the Statue of David:

HDTV in the US IS ALWAYS COMPRESSED. In Japan, they have analog HDTV but, in the US, it is compressed digital audio/video. "The video compression will be a variant of MPEG-2, and the audio will be Dolby AC-3 (basically a five-channel system)." from HDTV

just as a cover my ass addendum to my previous post (damn anonymous coward trolls). The above figures are for CCIR-601 compliance. CCIR-601 is the Encoding Parameters of Digital Television For Studios (ie encoding video into data usable by a computer). CCIR is the International Radio Consultative Committee a predecessor organization of the current ITU-T which is the International Telecommunication Union--Telecommunication Standardization Bureau. OK enough backing? :)

Heres a link in case you are bored and want to read all about CCIR-601.
