1. Philips Fluid Smartphone

No, this isn’t just another bendy bracelet from the 80s. The Philips Fluid smartphone boasts a flexible OLED display and doubles as a trendy fashion accessory for geeks while still allowing you to make calls.

2. Easy Tile Cell Phone

Remember all those hard-to-solve sliding tile games? Well, they’ve been transformed into the Easy Tile Cell Phone. That’s not all, “using a printing service, you could print an image onto the tiles, and then turn the phone into one of those sliding tile puzzle games.”

3. Coca-Cola Phone

Designed by Daizi Zheng, the Coca-Cocal phone is exactly as it sounds, powered by the sugary, carbonated drink. In other words, it’s sugar-powered and will supposedly last three to four times longer than its lithium-ion battery powered counterparts.

4. Flip Phone

It may have a simple name, but the Flip Phone is not just any handset. This phone features three super AMOLED displays that can be folded to form a triangular prism of sorts, in addition to Android FroYo and a front-facing camera.

5. HTC1 Smartphone

Think of the HTC1 as what a Windows-powered iPhone would look like, meaning “twin metallic end-pieces made of machined brass with a silver finish sandwich an inner slab of glass.” Simplicity was key and that’s why you’ll only find a single button on the front along with a camera.

6. Project Seabird

If Mozilla were to make a phone, it would be Project Seabird. Unlike any other smartphone, the Seabird boasts dual Pico projectors that enable users to project a full-size display or virtual keyboard. Plus, you get a removable Bluetooth headset that doubles as an IR pointer to boot.
