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.

Perhaps you're in the market for the fractal app he helped create.

Instant purchase. Thank you very much!

I think you want to link to the page for the castle: https://de.m.wikipedia.org/wiki/Burg_Rheineck.

It has a nice picture at https://de.m.wikipedia.org/wiki/Burg_Rheineck#/media/Datei%3.... That definitely has everything you want in a castle (tower, walls, courtyard, situated on top of a hill), but also seems liveable, with something resembling a house built next to the back wall.

I remember being awed by a demo of KPT/Convolver at the Toronto Macworld in 1994 or 1995.

Kai was showing off how you could take a blurry satellite image of a parking lot and do a "spy movie" style zoom and enhance to reveal a car's license plate, which was impressive back then.

The UI was just plain crazy, especially by today's standards.
