The images in the lock-fitting instructions at the Yale site have a disturbing Necker-cube effect, e.g. http://www.yalelock.com/14769.epibrw
In other news: Nils managed to travel 240cm sideways today. First he climbed up onto the side of a chair. Then I decided to try moving them around him; we have four chairs, but he ended up sliding past six widths. It's interesting watching him position his legs. There is a lot of jittery placement and repetition but the sum is a slight movement sideways, followed by giggles.
Later on, in the tub, he was laying back and the water was just that little bit too high (cute side-effect: foam beard). I decided to gently tip some water out and I had to laugh to myself as I realised what I was doing. It's not often you get to literally experience the (possible) source situation behind such an over-used analogy.
I've decided to continue my little blog-reading holiday for another week, at least until I get a little pet project to a reasonable state. So, world, if you've moved over to binary XML or started selling REST in SOA-clothing or even just invented another lolfoo, then, well, it'll just have to wait. Aren't I brave?
