On an impulse, I created a page on the New Babbage wiki that lists all the machinima and other multimedia presentations I could find. That list is here. If you know of more, I hope you’ll add them yourselves, or email me or comment here with a link. Enjoy!
(Please note: I did not include machinima that I really felt were advertisements of products, even if the products were created by New Babbagers and/or the machinima were shot in New Babbage.)
