Got a funky party coming up and need some light show grooviness to throw into the mix? If the party doesn't involve watching what's actually on the television (the collective souls at TV Squad gasp), you can try getting your hands on the Groovetube. This cool gadget attaches to your television screen via suction cups (I'd suggest not doing this on your non-glass screened TV), "converting" what's displayed on the television to colored blocks (as pictured).
