Love these videos for many reasons -- but especially because I love closing my eyes and listening to tops moving around on resonant surfaces like these drumheads.
Have gotten some great soundtracks out of large plastic bin lids (with or without the bottoms), large glass and plastic platters and bowls, guitar backs, and a tambourine, though the last was too small for comfort. Ball and textured tips give the most interesting sounds.
The audio is also one of the charms of rolling regen systems like the Top-No-Sis.
