I had a ton of fun! Last year I used four sources - this time I had 18 (that's counting Gensomaden Saiyuki and Saiyuki Reload Gunlock as different sources, though they're technically the same series). I couldn't have done it without a program called Video Hub App, which lets you make screenshot galleries where you can use the thumbnails to go to the timestamp in the video. Super useful when you haven't watched a source in a couple of decades. And of course I couldn't have done it without Handbrake getting all the clips in the same frame rate and aspect ratio.

Here's the result:
