If somebody asks me what was the nicest thing i saw from E3 2007, i can clearly answer: a 3d game for PSP and PS3 (probably downloadable), called “Echochrome”.
EchoChrome is based on the work of Japanese designer Jun Fujiki work called “Object Locative Environment Coordinate System” or short OLE Coords. As far as i can tell (his website is japanese, which i don’t speak) from various websites and blogs, he wanted to create the possibility for players to experience their own Escher-esque worlds. So what “echochrome” does, and what you can’t see from the screenshot above: it allows the user to move the camera arround this bizzare little world and the little figure moving arround, walks independant from the 3d world but depending on what the 2d projection shows you as a player. so for an example: if there is a hole in the ground, and you can see it, then the figure will fall down – as expected. if you rotate the camera so that the hole is invisible for the player, then the figure will walk past it without falling through. or even better: if the figure walks towards the end of a walkway, the player needs to rotate the geometry in a way, that the perspective projection looks like, another walkway connects/overlaps with the first one. and then: voila the figure won’t stop but pass the end of the first walkway and continue walking on the second. even if in 3d the walkways have a huge gap in between!
It excites me a lot, because on the one hand i love puzzle games and abstract visuals. and on the other hand it is the only game of the e3 2007 my girlfriend went mad about

Me and Yu-Chung both agree that the game is ill-suited for the PS3. Because of the simple graphics and analogue controls, it would fit much better on a DS or a Wii.
Actually I meant it slightly differently:
I find it would fit better on a DS but mainly because it’s portable. The possibility to manipulate the camera with a accelerometer might be interesting. Or total crap.
I didn’t mention the Wii, though I do agree with Krystian that the point’n'click interface (seen in the demo-video) is perfectly suited for both the Wii and the DS.
About PS3 I only said that I don’t want the console (yet?), and therefore it’s a pity that echochrome is coming out there. But hey, there’s this PC demo.
Reasoning with simple graphics sounds like that the PS3 is not supposed to have smaller games, which isn’t very reasonable.
Sorry for misquoting you.
Interesting, why do you think a portable console would be better for this kind of game? What about the PSP?
I think the main point of having so much raw power under the hood as the ps3 does is to be able to deliver graphics, which weren’t possible before. This is no such game. I see no point in releasing such game for PS3 only. Why not releasing it on PS2 and counting on backwards-compatibility? Oh right, that wouldn’t improve PS3 sales…
portable:
because it’s simple and small (single screen levels I guess) enough to be played on the tram. Yeah PSP would do as well, but I don’t have one.
Good point about backwards compatibility. It won’t help sales PLUS maybe it won’t run properly :p The PS3 exclusivity is also a better point than graphics. This would be great on WiiWare too. I dunno, it feels to me more like a download title than a regular one.
