Automania 2000 and Pan-Tele-Tron
YouTuber Phil Gray, who uploaded this rare Tex Avery documentary a while back, has posted more difficult-to-find pieces of animation online: the British animated shorts Automania 2000 (1963) and Pan-Tele-Tron (1957). As films, Automania is clearly the stronger of the two and the only one which I can recommend, but there are some fun design elements in the industrial short Pan-Tele-Tron which might make it worth a glance as well.
