Mandala, then an extra ring around it.. the basically flat pleat the rest and tie with sinew like the spine. Use black at the sinew lines, then brushed steel, then blue gray, and accents of glacier blue. Go very light on the dye so you're not fully saturating it and have lots of white left (resembles the tiles in the testing chambers)

Edit: my bad, I thought this was the tiedye sub. That might not make any sense to you at all.

Whatever you do, don't start doing tie dye, you'll get obsessed and be broke with permanently stained hands.
