Light painting is the process of using one or more light sources to fill in a single exposure to create a unique image. If you think of the light like a pencil to paper and then add tools like a Spirograph to the situation you might understand what exactly I am doing.
The light wheel is actually pretty simple and you can get pretty creative with it on the fly. It is made up of a bicycle wheel (any size, however I have found that a 20” BMX bike wheel is a good size), A set of battery operated LED string lights. (These can be purchased from eBay or if you are lucky around October through March you can pick them up at Target or IKEA (any store that sells Christmas stuff is likely to have them). The lights are attached using black electrical tape and I used a bike peg I had laying around as the handle.
