The gradient post that stood beneath the Southcourt footbridge at the north end of Aylesbury station. The post and the bridge have now gone. I'm not sure of its provenance - it may be of GCR, LNER, GWR or Metropolitan origin. The gradient of 1:2200 seems insignificant but it is actually quite noticeable; approaching Aylesbury from the north you have to apply a couple of notches of power in order to maintain the 30mph line speed. 21st April 2003.

Based on some of the manipulated photos I posted as abstracts, this is a completely made up image I created using Paintbrush, a free color-paint program on my Mac. I can see too many artifacts from the tool that my skill isn't up to dealing with. HOWEVER, the basic thought seems to have worked out ok. What I noticed in the manipulated images of the inside of a crab's shell is that having a gradient or progression in a limited palate going along one dimension, and then applying a second palate and shape in another direction was "interesting" to look at. So here's a spray-paint gradient in blue tones, upper left to lower right, with a poured color splater going right to left, fading from orange to bright yellow.
