[DIYbio] Anyone ever see electrophoresis where the gel was rolled?

I am thinking something like a pinwheel, or a rolled capacitor:

but instead of using metal, this would be insulator, and instead of
electrolyte, this would be agarose/gel.

There could be a few ways to assemble something like this that I can
imagine, starting with something as simple as a sheet of plastic or
rubber, then dispensing a line of molten agarose down the center.
After hardening, the sheet would get rolled. You'd then need some
fixtures to hold the roll so it didn't unravel, and also you'd need to
ensure the spiral-path didn't short out around the edges. Maybe the
unraveling-preventer could seal one end, while the other was upright
and exposed to air, allowing you to then pour in running buffer.

Anyway, I'm just thinking of unconventional ways to emulate capillary
electrophoresis, mainly so I don't have to purchase a traditional gel
box... but also thinking to reduce setup/cleanup time involved, and
reducing reagent consumption.
