In my quest to try to have at least one of every possible clipart needed by anyone uploaded to this openclipart.org site, I found a cool old public domain image of an Ainu man from the 1890s on Wikimedia and hand colourized it myself. After that I synthesized it as a vector image for the future. (If you don't know, the Ainu people are some of the aboriginal people of Japan.)

This was made using an old cotton bag for the rumble of flames and then two different types of plastic wrapping crinkled up. Then it was put through audacity changing the speed and pitch separately for each track, then mixed and rendered. I am quite pleased how this turned out.
