SpacePaint is a set of 7 colorful toys for the card10.

* CYCLE between the different modes with the BOTTOM-RIGHT button.
* RESET the current mode with the TOP-RIGHT button.
* PAUSE / RESUME drawing with the BOTTOM-LEFT button.

* Current mode is displayed on the LED bar above the screen.
* Blue modes use the orientation sensor; red modes don't currently use any sensors.
________________

Mode 1: Draw on the screen by adjusting the orientation of your card10.

	Note: The pencil should move in the direction of gravity, but the
	orientation sensor sometimes gets inverted (at least on my device).
	If up is down, try rebooting your card10.

Mode 2: Like Mode 1, but mirrored for satisfying symmetry.

Mode 3: Modulate a sine wave by changing the orientation of your card10. Y-axis controls amplitude, Z-axis controls frequency.

Mode 4: Like Mode 3, but the waves persist on the display (rather than being cleared with each display update).

Mode 5: More iterating waves, influenced by orientation sensor.

Mode 6: Iterating wave screensaver. (Non-interactive.)

Mode 7: Iterating wave screensaver. (Non-interactive.)
