Try out revisions and multiple designs. I decided to give this as a gift to a friend who loves Fight Club. Not wanting to force him to be committed to buying 9volt batteries the rest of his life, I jacked the power from an old cell phone charger. Had I originally intended to do this, I wouldn't have built the 5volt circuit regulator as it's kinda unnecessary now. I printed off a new image and colored it in with Sharpie. Cut it down to size and viola, a personalized awesome wall light thingy. Added are some other image ideas. Any image will work. I prefer black and white graffiti stencil. But feel free to try out whatever art you are into. For a total cost of under $20 US dollars, you can get crazy printing different skins and changing your awesome wall light to whatever suits your daily mood.
