> and have been developing a different online experiment each year until 2017. The 2013 experiment was by far the most successful. It allowed visitors to draw their own postcards with 6-axis symmetry, creating a snowflake-looking drawing almost no matter what was being drawn.
Nice. What were the other experiments you tried doing besides snowflakes? Any reason they didn't work out?
I was just messing around with this and experimenting with the features, when a human shape slowly started coming out of my unconsciousness. At the end when I realized what was coming out, I strove to finish, and it turns out quite angelic.
I had a similar idea. I guess face shapes are natural given the vertical symmetry, and since the outcome is a bit random our bias towards seeing faces even in vaguely face-shaped patterns helps.
Hi, the app does support up to 11 multiple touch points. I'm not sure if the API was around to implement it on the web at the time this website was made, or if it was I wasn't aware of it. Multitouch on the iPad works with both fingers and the pencil.
