Thanks, I have to admit I really just ripped off Google Play Music's interface. The square icons were inspired by the album art for Ryuichi Sakamoto and Alva Noto's "Virus" series of albums. I made a program which generates them for me. The way it works is to split the square into squares, rectangles, and triangles, and then randomly choose which to stroke and fill.
This sounds really interesting. However if you do want to distribute this widely, I would check if they have any patents on their devices because stupid American IP laws.
