I was in a bar tonight and there were these guys with these weird LED gloves and were doing this little show where they wave their hands arounds and it looked really awesome. Seems pretty simple. They have 16 watch size batteries linked up to super bright LEDs. I kinda thought that was a good project to try instead of buying a pair for 100 dollars that are considered quality. I really don't even know how to go about this.
They're called Light Show Rave Gloves.
Here's a video of what they look like afterwords.
