you wanna see some crazy shit,hook a camcorder to your tv.then turn the camera on ,now point the camera at the tv which is showing what the camera is taping.it turns into like a thousand tv's,and if you start turning the camera side to side you get a crazy vertigo affect,try going close to the tv and father back,i got dizzy jus watching this shit
kinda on the same note,i know you can do it with a micro phone,but i used to do it with my electric guitar,put the guitar right in front of the amp and start tapping the guitar with your palm,and the sounds commin out of the amp will then make the strings play a tune,its like recycling sounds,you can get some insane sounding whacky shit yo.
