I decided to drain some of the water out of the OD&D pool and dump it on the people swimming in 4E, and the result can be downloaded from 4shared.
You know how elves used to be able to choose whether or not they were fighters or magic-users, and be able to switch "when the moon rises" (or whenever)? I decided that the 4E Eladrin should gain that ability; and trying to keep both the description and the usage simple was no easy feat.
That was a pun. Enjoy!
