Got four meters of green fabric in Nippori's fabric town the other day. A two meter sheet of at a photo shop is like 10000円/$100 or something. I got the four meters for 400円/$4.

Finally got around to doing a green screen chroma key test and it totally worked. Just need to figure out some way to do the lighting better and in a way that is portable. Also, need to get my head around getting the edge on the video being cut out.
