OK, this week’s sketch is admittedly a bit wacky, but it’s just one variation of a block-based design that I thought was worth sharing.

The block itself is made up of one large and five small drunkard’s path units. On its own, it looks a bit like a UFO or some kind of sea creature (although it also reminds me a bit of the Shine Dome. Or maybe Thing from the Addams family!). But when one block is positioned next to another block, those drunkard’s path units combine to create interlocking crochet-hook-like shapes. Can you see them?

Rotating the blocks creates a different kind of movement, but those interlocking hooks are still there.

I simplified the design to highlight those hook shapes, although I don’t like this version as much; the balance of the small and large drunkard’s path units adds to the design, I think.

I do have a soft spot for two-colour designs where the same motif or shape appears in both colours.

This week’s design could be made using lots of drunkard’s path units – not quarter-circles, but the ones where there’s a bit of a gap between the curve and the edges of the square.
