I know this is not a typical math question. I also thought about asking on superUser or stackoverflow but I came to the conclusion that I have a higher chance of getting an answer here on the math stackexchange.

I recently have read about the tool named f(z) from lascaux graphics which helps visualizing complex valued functions. This seems to be a very nice tool in complex analysis. However it looks a little bit outdated and I cant find anything like a website or something. Do you know this tool and/or have any idea where I can find additional information about it?
