Im creating this tread to find trippy toys that you see at different festivals and concerts. Im stocking up for Bonnaroo 2010 and am looking for a specific 'toy'. I was at Pretty Lights in Knoxville (which was fucking amazing by the way) and saw this group of people all wearing 3D glasses and went over to check it out. One guy in the group had these two handheld glowing/flashing blue/red balls that looked almost static-y and electric. It looked sweet by itself but with the 3D glasses on it was like looking through a kaleidoscope. One of the coolest 'toys' I've seen. Does anybody know what there are called and where to buy them? Anybody else seen these?
