A designer that goes by the name BloodRabbit submitted a phone concept idea that I found so pleasing I had to share. Given current technology the idea is practically impossible, but that didn't stop him. Here's more:
In traffic on the way home from work I envisioned a phone about the size of a credit card, completely see through (okay, not completely, but you get the point) and still usable. The top of the question mark shaped string/tube is the menu button and directional keys.
I'm a firm believer that a cell phone should be functional above all else, but I don't think I've ever seen a more sophisticated design idea. Sure there wouldn't be any e-mail, texting, camera or other bells and whistles, but it has a futuristic flavor I haven't seen anywhere else.
