Akai Ito

DigiCon6 ASIA Awards is a competition for short films of Asian origin, established in the year 2000 by TBS.

Most of the winning entries from recent years can be viewed for free on the official website and youtube channel:

There is an English version of the website as well, but it doesn't list all the Japanese regional winners. Instead, unlike the Japanese version, it does have winners from other regions:

This list is by no means comprehensive, as many of the winners don't have a MAL entry yet, presumably because the creators might not be established in the industry.

Part 2: https://myanimelist.net/stacks/51870

Anime that were created by a independent (indie) animator or group of animators.

Only including anime released in the modern era of anime, i.e. after the 1963 release of Astro Boy. Focusing on anime that were released after 2000. Not including music videos.

Not aiming to be comprehensive, but feel free to suggest additions.
