New kilt: Volcano tartan!

[Tarheel]

So, to add to the uber nerdy-ness here, when the pleats open up, it’s like when the chilled dark crust of a lava flow cracks open to reveal the hot lava underneath or, on a bigger scale, when the surface of black basaltic lavas in Iceland rift open and new hot, incandescent lava is revealed

I remember when this was commissioned. You described your vision of how the "flash" from the pleats would be compared to fissures and vent holes. You described it perfectly then and now I can't wait to see the kilt in action.
