Lightcomb (aka Pushbroom)
A column of lights attached to a rod (ranging in size from a comb with tiny
lights on each tine to a broomstick with Christmas tree bulbs) and
connected to a microprocesser that causes the lights to flash in
programmed patterns. As the rod is swept sideways, these patterns
form words or images (as programmed) - an effect similar
to that of waving a sparkler around, and best viewed with a long-exposure
photograph. For example, to generate an H, the following sequence could
be used:
1. All lights on
2. Centre light only
3. Centre light only
4. All lights on
Thus, we'd see:
