I Just made this today from a third party xbox 360 controller, I took apart the controller for the LED's and glued the ABXY buttons back in and taped over the trigger and bumper holes
The bowl is a socket, its really just for looks, its awkward to light and hits really harsh I just made it because I could
lol good answer before you get flamed for having made a bowl out of something other than glass. Cheers.
