AHh gotcha.

Well yeah I reckon you render a full custom 4004 w/ koru patterned transistors into about 4m x 4m stained glass panel. Would look good as the foyer panel for the CS dept at the University of Waikato

Probably best to tape it out to https://tinytapeout.com/ first

Do they support curvilinear cells?

The simple openlane flow just uses standard cells, but you have the ability to just tape out polygons so curvyish is possible

(I already have a 4-bit CPU there)
