[...] So, this is my first stab at coming up with something visual and it's in the same vein as Dewey Blobs… [...]

One more variant -- this one links together items that were borrowed at the same time. So, if I'd borrowed a 005 and a 130 at the same time, there'd be an arc joining both together. It's quite a busy graphic, so here's a version without the blobs.

Heh heh -- how could I not resist turning it into a movie? :-)

I've added another version to Flickr which uses an offset of 12 to the start of the curve. This smoothes out the boundaries between each block of 100.

I've added a version using the curve to Flickr. You can use the slideshow function to compare and contrast the layout. If you're struggling to see the flow, then here's a crude drawing to show where the blocks are.

I'll have a play around with using a Hilbert curve tonight, but here's what the Dewey layout would be. As a 32x32 grid gives 1024 points, that leaves a bit of a gap at the end of the curve.

Thanks Tom — might give that a go! Looking at the Hilbert curve, it appears to double the number of points on each axis on every iteration, so there should be a curve for 32×32. Amazingly, there's even a suitable Perl module available
