Johnny Chung Lee

As far as hacks go, the Wiimote projects from Johnny Chung Lee are among the most interesting.  After seeing his hacks, I went out and bought a Wiimote (£20) and some infra-red diodes (i.e. sensor bar), and had a play myself.  While I wouldn’t make any Apple-style statements about his ideas “changing everything”, they are certainly worth a look if you want to dabble in low-budget robotics, motion tracking or virtual reality.
