The outside board known as /tg/ (if you don't know what that is, don't ask) has been working on some power cards for D&D 4e. Since a good deal of the 4e supporters and optimizers on that board are interested in Touhou, these power cards have been modeled after the Touhou TCG, Rumbling Spell Orchestra: http://1d4chan.org/wiki/Touhou_Power_Cards
As such, the cards emphasize preserving the aesthetics of the Rumbling Spell Orchestra cards over ease-of-use. Still, it's a cute little project for anyone interested in both Touhou and D&D 4e.
The project turns cards like these (they're thumbnails, click on them for the full pic):
