|I enjoyed the slashdot discussion(s) on whether this is actually "waste electricity" or whether the bulbs are actually drawing small, illegal amounts of power from the lines. "Roscoe P. Coltrane" and others make a pretty good-sounding case, from a physics standpoint, that it's the latter.
That's a *really* important issue, from an art standpoint. Is it an ecology-minded piece or a "free" light show?
It being slashdot and all, they also managed to work in analogies to downloading and other digital culture issues.
