Yeah I was thinking that, since they are still using pretentially toxic materials in the making of the electric components inside.
Still, that'd be kewl to have open to you. I can think of many more uses. For example, playing a piano song. You could have a program download, and if the chip could recognise what your eyes are seeing, basically tell you whats coming, etc.
Other uses in songs, etc. Lyrics appearing, electronic manuscript.
