I started being more random in month 3, including doing a colour pencil horse a day to make a picture I vaguely thought was going to be rainbow. I also played a fair bit with markers from the smart art box. Also lots of legless and strangeness…how far could I go and still have it be a horse? Pretty far, as it turns out.
I also started drawing them as stick figures and it occurred to me I used to do exactly those figures at high school in my notebook margins. Freak me out. That has been lying dormant since Rick Astley was charting.
