Cool flashback to the nineties. I remember spending hours at school in '97 or '98 obscuring class pictures of everyone as a gag. Approved by the teacher who also loved this kind of stuff.

Here's a link to the wikipedia article about the developer, Kai Krause. https://en.wikipedia.org/wiki/Kai_Krause

He sold the software to Corel (remember them?) and bought a castle in Germany. https://de.wikipedia.org/wiki/Bad_Breisig (the German article has more pictures).

Would be fun to have these tools back on an iPad to play around with my kids.
