• i. It makes the pages easier to browse - I hate waiting for pointless images to load or not being able to bookmark a page within a frame.
• ii. My sister, Jenny, works for the RNIB translating documents into braille. More about this: No fancy graphics

To get around this I been trying to convert images into different forms. Topology and graph theory seem to work quite well for webpages and database structures. I have some rough notes on graph theory, including a web of cube topology.

One of the areas we studied in astrophysics was "non-linear dynamics and chaos". This included determining whether a number stream (time-series) was periodic, chaotic or random. Some of this was done using phase-spaces and pseudo-phase spaces. (This has links to mental representations in the work of Ian Stewart and Jack Cohen and the work of Steven Pinker).

I've done various graphical representations of chaotics maps (such as the logistic map) using c++ programs - I'm now trying musical representations. Music seems to work for number streams (of real numbers and chaotic maps anyway). I've completed a midi file of the first 1024 notes of pi.
