Peano fungus by markdow Peano fungus by markdow
(SEM micrograph, false color)

Peano fungi are slime molds, cultivars of Physarum polycephalum. They can be genetically engineered to grow in space-filling patterns on silicon for use as a lithographic mask. Each colony expresses a unique protein that is integrated into cell walls, which are then baked onto the indium gallium nitride (InGaN) substrate. Monolayer graphene is overlaid and selectively washed off to form conductive paths. What appear to be through-hole solder pads are micro-machine registration points for surface mount components.

The pattern is a similarity tiling based on an anti-symmetric variation of an unusual space-filling curve, tiled periodically; see basis pattern of its construction.

This cultivar was used as an artificial environment for testing robotic camouflage:

To quote a friend, "Oh, that is pretty dang cool!" Boy howdy, do I agree! Peano fungus by ~markdow demonstrates that sometimes the math behind a fractal is just as artistic as the colors,textures, and composition. I feel that all of this has hit the nail on the head. Great work from an enlightening and informative gallery. ( Featured by Platinus )

Was this made with a program (Ultra Fractal, Apophysis, etc...) or was this done by pencil-paper math and digital drawing? o3o

The theme was done with MATLAB, but mostly it done in an image editor -- cut, copy, paste, paste, paste .... then fill for the colors.

I have this irrational fondness for fractals that look like textiles, and boy does this fit the bill. My one critique is that I wish it had even MORE detail, to look even MORE textile-esque.

These fungii are used as photolithographic masks for electronic circuits. What you mistake for through-hole solder pads are actually registration points for surface mount components. But yes, it will still require some nano-machines to line up the smaller ones.

I can't tell where the fact ends and the fiction begins, i.e. are such spacefilling curves really used in electronic photolithography, fractal antennae (hilbert, peano etc.) notwithstanding? And for what purpose(s)?

Regarding the image, I dig the palette and the rounded terminals. Very bold and would make a good centerpiece to a maths department reception...

Yes, fact and fiction are blurred. Circuit layout designers do use space filling techniques. Now synthetic DNA can be "programmed" to self-organize regular structures, even fractal structures.

Lithography is limited by the size and shape of the things it can make, and it is primarily a 2-D process. It won't be long before this kind of space-filling algorithm will be encoded into the molecules that are the material of the space-filling structures.

This fungus is a fiction, but fungii do space-filling -- anywhere that nutrients are available. It's not unbelievable that fungus could be engineered for this purpose. Here's a natural "Slime (mold) Design (that) Mimics Tokyo's Rail System".
