Datasheet

The texture needs to go in a data folder inside your Processing sketch's folder. Save it as

ring.png inside this folder.

Now let's try out this texture! The sketch has a few new parts:

colorMode (http://adafru.it/cWc)() switches to the Hue, Saturation, Brightness color

space.

loadImage (http://adafru.it/cWd)() loads ring.png into a PImage variable.

drawRing() draws our texture with a particular hue, intensity, and location

Temporary code in draw() puts a single ring at the mouse cursor location

Try it out. Move the mouse around, and get a sense for how you can use textures to control

the shape and the behavior of the LEDs.
