Yes Ditto - David is a master in dynamic graphics manipulation and
animation.  If you appreciate the mathematics of poetry, on David's
homepage are some quite exquisite translations of Rainer Maria Rilke's
and Charles Baudelaire's Cat Poems by Alice Parker.

There's even a wee bit of a Rule 30 Cellular Automaton in his views on
Nation States?
