http://www.thinkgeek.com/electronics/musical-instruments/a02a/ This is a link to the first top left image....You can view a you tube clip of the box in action. Its basically a touch pad, plus a synthesizer...you can control sounds with it... 'Move your finger from left to right to change the pitch of the note, and up and down to change the sound. But musical sounds are only the beginning, the Kaossilator can also be used like a drum kit with dozens of built in beats and drum sounds.'
The third image....black and Grey...rectangular....
'The Stylophone is a miniature stylus operated synthesizer invented in 1967 and used by such iconic musicians as David Bowie, Kraftwerk and Erasure. It features a metal keyboard played by touching it with a stylus. Simply remove the pen and tap any key for classic synth sounds. There is a switch to add vibrato and you can choose from one of three different retro organ type sounds. The tuning knob on the bottom allows for some pitch-bend effects if you must. The Stylophone is one of the simplest electronic instruments you will find, but it's minimal style is a big part of its charm. '
In this picture....pop up speaker, for Ipod, or other mp'3 device.
Also a USB Drum Kit....drum pad that plugs into your computer...its flexible too, it can be rolled up....
