penrose

After six nights in the dark, my power returned last night. I am immensely grateful that my house escaped the widespread devastation that can be found in my community. I've posted my photos of the devastation and its aftermath to Flickr; I did not seek out damage for photography purposes, but it was everywhere I went. it took a few days to rescue Tenzing from the vet's, thanks to this mess in front of their building:

I've made no secret of my intention to do a large Penrose quilt, but I had a sinking feeling a little while ago that I should perhaps consider doing a trial run first instead of cannonballing my ass into the deep end and potentially ruining a lot of fabric that can't be re-purchased here in Huntsville.

I've been more than a little obsessed with tilings ever since Jacob pointed them out to me a few months ago, and I've been quietly storing up tilings I think would make great quilts. At first, I asked myself why other quilters hadn't tackled these visually stunning images for quilt purposes, but eventually it sunk in — because they're hard. They're demanding. Their continual broken and rebroken lines mean you never get the luxury of straight, long seams or 90° angles. They require piecing odd and funky angles on small pieces over, and over, and over again.

A Penrose tiling is an aperiodic tiling consisting of only two tiles and containing five-fold symmetry. The wikipedia entry for Penrose tilings has good images and information about it, plus a couple of photos that help you see how the pattern might look when colored in.

I am aware of the existence of a few small Penrose quilts, but from examining the photos it looks like they contain at most three iterations of the tiling. Not surprising — it's hard to find images to work from that have more than three iterations. I had to install Inkscape and use the instructions on this page to render out seven iterations of the pattern, but it's in readiness for when I decide to tackle the pattern.

Like I needed a new obsession.

On Friday afternoon, Jacob introduced me to Penrose tilings, which were entirely new to me. I was completely fascinated, running off in a multitude of directions to learn about things like 'aperiodic tilings' and tile patterns in Islamic architecture, and by Saturday I was hooked.
