Clark Griswold, eat your heart out. If it's Halloween or Christmas, you can be sure that Alek Komarnitsky has bedecked his Lafayette home with the most incredible light display around. After he caught flak in 2004 for tricking visitors to www.komar.org into thinking they could control his Christmas light show (it was an elaborate online hoax), Komarnitsky figured out a way to actually do it. Now folks can log on to his overly stimulating website during the holidays and turn his thousands of lights on and off. It may not make the neighbors happy, but since Komarnitsky uses 100 percent wind energy, makes carbon-offset contributions for the electricity his display consumes and allows online visitors to donate money to celiac disease research, this is insanity for a cause.
