If you feel as though you need a bit 'o creative stimulation, why not have one of your old digital cameras converted to an IR-only camera.

Middle - IR picture (straight out of the camera)
Bottom - with a few Channel swaps.
Get a discount on your IR conversion at Lifepixel by using this code upon checkout: Rick Sammon.
