CURRENT (HOSED)   allows the user to paint with a spray of ROYGBV pictures, a handful of images for each color; in-betweens, such as reddish-orange, are created by dithering. The spray scatter and spray rate are adjustable.

It was so sad to see electronics components spread out on the canvas, all suggestive of electrical functionality, circuitry, and blinky lights -- and then to be denied any taste of it. Therefore:

• When you apply a voltage, the LEDs light.
• ...unless they're reverse-biased.
• If there are capacitors in the circuit, the voltage decays up slower (evidenced by LEDs lighting more gradually).
• If there are polarized caps in backwards, they'll crash and burn.

Not added: LEDs without current-limiting resistors should melt. Alligator clips on the screen should indicate whether there's power.
