Fantastic work! * Dirk Lattermann <dlatt@alqualonde.de> [Jun 12. 2015 14:42]:

Yes, I already considered this. Maybe sometime, it'd be nice!
It was a major effort finding a round drain. Only square ones seem to be readily available (and affordable). When my plumber finally came around with this circular drain, it reminded me at once of the metal samples a water jet cutting company had shown me when I inquired them about cutting the tiles (very expensive, but would have saved much time and grief glueing).
For this round drain, I paid about 10 times the price of a square drain. A custom designed penrose drain plate will be expensive, and I have not figured out how it will look like when the rhombs are rather small to leave big enough bridges for stability.
We should have (laser-)cutters powerful enough for metal at our school. I'd need to know the dimensions, mostly the thickness, to be able to ask around.
