Someone on Making Light mentioned a site called
LibriVox. It's a sort of Project Gutenberg for audiobooks: people record public-domain texts and release their recordings also into the public domain. I've just finished recording the part of Richard Planagenet (Richard III's father; people who've played
Kingmaker will remember "Richard of York") in Shakespeare's Henry VI trilogy, and had a glorious time chewing the scenery in his death scene. Just more fun than anyone ought to be allowed to have.
(I've also been recording the part of Lord Henry Wotton in a dramatic reading of The Picture of Dorian Gray, which is likewise great fun; Lord Henry gets to say all sorts of wonderful Oscar Wilde epigrams.)
