Denim

Now, where did I put my change?

Stargazer

Blurring the gap betwixt crisp and nebular.

Bloodstone

Sanguinary shades.

A breathtaking view of vulcanism

Don't get too close!

At the mountains of madness

You'd be crazy to climb!

A touch of ironstone

Geological using a pale background.

Disorientate

Sway to the left, sway to the right...

Oddly uneven

An object-lesson in asymmetry.

Spots

Old framework with a new base.

Gneiss

Nice?

Gödel, Escher, Bach

Infinity both ways...

Droste mat

A nice cup of drinking chocolate to go with that?

The shadow over Innsmouth

Something, which oughtn't, stirs...

The Tannhauser gate

As one dimension folds, another explicates.

Shimmerness

Tiles go wild!
