Ah thanks! I was just looking for validation of some song lyrics... "a notch
in space and in time, an endless hole for the scree, event horizon in the

idea made any sense. So I thought I'd ask a nice, simple question onlist...
btw, any idea how I can get hold of White Abacus? I've tried local
bookshops, including Known Space, but no luck.
