Ollie Wagner sends word that he has release both of his Spencere apps, Menuet and Art Collector, as careware. Over on his site, you can get both of the apps for free, as long as you promise to donate to the charity of your choice (he's listed eight good choices if you don't have a preference).
We've covered both before-- Menuet is a pretty iTunes controller with a few other features built in, including Last.fm support, themes, and a sleep timer. Art Collector grabs artwork from Amazon for your iTunes library-- it's a little useless, because iTunes now does this for you, but if there are a few covers iTunes can't find, maybe Art Collector can.
Together, they used to run around $13 (although Art Collector separately was $7, and was originally bundled with Menuet). If you've seen these before and never gotten a chance to try them, here's it is, and hopefully you can help out a charity as well.
