AccioBrain is the best Harry Potter fanart site around (with possible exception for DeviantArt and other communities where there's more than one contributing artist). The website is pretty to look at, easy to navigate and just plain entertaining!
The layout is simple, potterific, wellmade and cute! Loading the actual art can sometimes take a little bit long on a slow connection, but once they do load they're defenitally worth it.
There are sevral art-sections on the site, all full of great quality work by the talented Heather/Makani who owns the site. The "general" section is filled with gorgeous depictations of characters, scenes etc from the books (and possibly some from the webmistress's mind). The "silly" section is my favourite, as it's riddled with humorous pictures and comics, internal jokes, parodies and all other forms of funny goodies one could wish for. There's also a page for the online project Fanart100, which is well worth a look to see this great artist's interpretations of the Fanart100's keywords. There is also a commision section (though she is currently not accepting commision requests, which is too bad or I'd probably request one) and an (in progress) section with chapter-by-chapter illustrations of the Half Blood Prince. Oh and for any artists out there she has some spiffy tutourials too!
So, to sum up, if you're a Harry Potter fan and an art fan, this is defenitally a site to be visited, bookmarked, and visited again!
Heather draws a lot of Harry Potter fan art. A LOT.
