From the pages of MAKE:Blog, a one-pound CNC-machined desktop tape dispenser (http://acuteaero.com/2010/06/03/the-most-advanced-scotch-tape-dispenser-in-the-world/):

It was a part from the advanced CNC class at Laney College, but has some potential for those of you looking for a small, relatively simple project for a Christmas gift or similar. After all, unless your subject really likes nuts, how many people will end up using those nutcrackers? :D

and here I was, expecting to see a servo-ed dispenser that measures out the tape 0.001"!

Title reminded me of a demo the last day of the CNC week at Galesburg
3yrs ago where a fireworks taping device was shown. The completed
shell has to be wrapped with masking type tape to a depth of 6-12 layers
IIRC and the demonstrator had rigged up three axes of rotation. Tape was
started and one axis ran at higher speed, another a bit slower and the
third jogged periodically resulting in a fairly spherical 100% coverage of
the shell in a short time. Shells are tennis to soft ball sized and meant
to be fired from computerized mortars at fireworks displays.
Simple and ingenious application of MachIII.

Huh. It's no good for high-speed operation. They didn't put ball bearings on the center shaft. :D
