To be honest I haven't yet read the original article, since it's huge. It seems to aim for something compareable.
Here's my one https://fingswotidun.com/blag/shaderpic1/ You can drag and drop images to set a new goal image.
I used coloured triangle pairs with a small set of combination operations and a soft edge falloff.
A write up of sorts at http://blag.fingswotidun.com/2016/05/evolved-images-using-sh...
I'll look later when the rush dies down to see how they compare.
[edit] I just realised it's been almost 10 years and I'm back to doing the same thing in a different domain. Right now I have a computer training an AutoEncoder to make the best 128 byte 32x32RGB images it can.
I had to dig up the original post by Roger Alsing[1] as it seems to have inspired a few people. I hadn't thought of evolutionary algorithms being used for image compression before; evolving from pixels to polygons creates a tool artistic expression, but also has utility for data compression (even if it's lossy). I wonder what other data formats could be compressed via evolution!

I didn't notice a link to any code, would you be open to sharing the code? I'd love to take a look at how you did things and play around with it myself.
