Bulgarian/Eastern European Animation

I saw an excellent program at the Roxie Theater in San Francisco this morning that included the following cartoons:

Baby Dreams – At the Airport
The Eagle’s Feather
Beach
Fantadroms – Rainbow
Leopold’s Television
Three Russian Shorts: Mosaic, Scatter Giovanni, Rout
Baby Dreams – The Auto Factory
Fantadroms – Ice Cream
Russian Winnie the Pooh
Hedgehog in the Fog
The Disobedient Kitten
Skatampanti: Looking-Rhymes

Most were great, some were excellent. Except for one that took Silly Symphonies head on, they were quite different from American (and Japanese) animation in terms of story; wildly different and surreal, most of these without dialogue. There's at least one episode of Fantadroms on YouTube:

It wasn't one of the ones that played at the theater, but I'm sure it's good as well. I am looking for more of them if available, but am especially looking for more of the Baby Dreams series. This DVD:

http://www.amazon.com/Best-Bulgarian-Animation-Nadejda-Iantcheva/dp/B00004S897/

has them on it and so I'd recommend it to anyone here. But it only has those same 2 from Baby Dreams. Anybody have any leads on more?

I've been looking for that, actually. This is the version I remember, it has some nice space music atmosphere to it

Found this playlist too, which seems like it has most of the Fantadroms (11 plus 2 which were deleted), hopefully the link works:

Would really like to find more Baby Dreams though and other things by that studio. Oh, hold the phone, got the Airport one at least (which I already saw):

Well worth watching! Will dig for more.
