I made a Madoka Magica AMV using a parody someone else made of Do You Want to Build a Snowman. Major spoilers for anyone not familiar with the show. Also, you'll have no idea what's going on.

I also finished rereading Homestuck and finished reading the archive of To The Stars (a rational Madoka fanfic), both of which are long enough that I consider reading it to be impressive. I can't imagine the people that wrote these.
