This is a mosaic that was made with water, flour, salt and a little bit of color. It is brilliant.
I went and had a meeting with the women in charge of the cultural center a few weeks ago. We talked about possibly getting a machine to cut tiles for mosaic art for the kids. I helped her search on the internet for these machines for a couple of hour, all of which were pretty expensive, and then resolved to come back the following day to take up the conversation again. I returned and was shown this. Genius. Pure genius. You can get by with a lot less than you think.
