That is just batsh*t crazy... and I love it!
Absolutely accurate! Thanks George.
They are not, Tom. I'm relying on the weight of the head units themselves plus the weight of the sand-filled cylinders they're sitting on. The sorbothane between the head and the cylnder is quite sticky and keeps the head from sliding or moving at all - as they sit. But the cylinders themselves are not fixed at all to the desktop. Each glass/head tower is pretty damn heavy and isn't at risk of falling over or anything.
Net-net, they could be
knocked over/off. This would require either (a) intent or (b) lots of alcohol consumption. I would not do a setup like this in the living room where there are kids and random people around. Everybody stays out of Doody's office
