Great job once again. Presentation is always an essential part. As most of the users above, I definitely like the 3D logo. I'm trying to learn Cinema 4D a little more, but I just wouldn't know where to start.
Heh, this comp is old and crappy...but I used Cinema 4D, a 3D program, to do the renders.
I've used Cinema 4D, 3D Studio Max, and Maya (and a bunch of other specialty packages etc.), and Cinema 4D is BY FAR the easiest to learn. It also integrates really well with Adobe products, and even uses a familiar layer system.
Max and Maya are far more popular in the CG industry, but if you just want to learn the easiest 3D program out there, try C4D. And most 3D apps share many similar conventions, so once you learn one, it's much easier to learn a harder one. (I started in reverse order of difficulty, actually...Maya to Max to C4D. Wish someone had told me about C4D before Maya scared the crap out of me!)
the 3d visualisation would look great if it was like the glowing sign on street. you know if you have a shop and they have the thinge above the front door. (bet it has some name, but in fact i cannot remember it even in czech )
Thanks everyone for all the comments...I feel it aids design/branding when you can get a sense of how a tiny vector logo translates to different media in the real world. I'll be doing more of these studies very soon.
