The Julia sets
of polynomials z³+c, for c varying along a curve, stacked on top of each other. The curve ends at 0, so the stack ends in a circle and you can use the thing as a fancy little bowl. The polygonal approximations of the Julia sets have been computed for 14 backwards iterations.
When printed in porcelain, this product would be food safe and make a dish or bowl for food. However attempts to have it made in porcelain have failed. What a pity! Maybe you can apply a durable food safe varnish to the plastic version? I haven't tried that yet. The thin-walled version
would be better for that because it's cheaper and has more detail.
