Technical notes
This is an elastic design with one or two columns. The design uses a simple colour scheme with some subtle gradients in the headers [h2 and h3]. Typography is simple - two fonts only.
Akira maintains the site himself - something that is easy to do, because of the separation of content and style [into style sheets - CSS]
For those interested - the background graphic at top left of each page is a cross section through a 14 element lens, showing some rays being traced through to the film plane.
