Only those into partying hard should pay attention here, but stick around for the bad jokes. Lightcast is basically a house for 33 multicolored LEDs which will project onto your ceiling to – wait for it – the beat of your music! You can hook up your iPod, DAP, Discman, or whatever makes a noise and has a 3.5mm jack. It also includes interchangeable mirrors and reflectors for different light patterns. Fantastic. I’ll get the glowsticks, you bring the candy beads.
