Designed for Chroma but works without. Tested in emulation only.

Re: OpArt for the ZX81 with Chroma
Nice! I've added a link to the program from my website.
One issue that caught me out for a while is that the program only runs when using the edition 2 ZX81 ROM. With an edition 1 ROM the program crashes with error code C/9510.

Re: OpArt for the ZX81 with Chroma
It has to do with differences in the "expression evaluator" between the two ROMs, at 0F55 in edition 2. Any app using the evaluator, such as Hot Z, will crash. Try this on both ROMs PRINT +1.
Unfortunately, there's no easy work around for this.
