This installation looks fantastic:

Five modified toy pianos circulate the gallery on five elevated wooden tracks. Each piano is equipped with small speakers to play amplified sounds picked up from conductive tape on the tracks. Each piano also contains small motors which intermittently spin to strike the toy pianos’ tone bars, adding acoustic elements to the overall soundtrack of the work.

Needless to say, the idea of toy pianos riding atop magnetic tape and picking up samples as they go is a brain-tickler.

[p.s. I disappeared again, due to the curse of saying “I’ll be back” on one’s blog. Turns out the 1st year of a PhD program is work-intensive. No promises, but I will try to squeeze in the funs here as much as possible.]
