The "Maple Phone", designed by Hyun Jin Yoon and Eun Hak Lee, is a compact wooden phone made of African Blackwood. The phone appears to be a simple block of wood until touched, at which point its touch-sensitive buttons light up when you touch them. It measures 4.5 x 10.4 x 9.8 cm it has an MP3 player, and a digital camera. It also has a display that is placed at the back, that slides open.
This phone concept is not in production yet, but if it is created, it will be available for an affordable price due to the low cost of the materials used.
