Oh look, an impossible figure! Still not sure about that term in English, it’s pretty much a direct translation from Swedish. The other word would be illusion, but that seems so generic or ambiguous. In any case, long since I posted the last one. Long story short, hectic life, software problems, computer crashes, tired of posting and then time runs away an entire year. Nuts. In any case, new computer, new year, time to get this thing up and running again :)

It’s great to see this series return, thank you!
Thanks! :) Yeah, I have always just called them that, but it was more a direct translation than anything I had looked up!
