I first started out with the general search of "czech animation" and waited for the Google results. Per usual, Wiki turns out to be a great point of reference for topics I know nothing about. I went to a list of Czech animators because that would allow me to conduct separate searches for each artist without depending too heavily on Wiki. The biographies on each is generally short, but they provided names of famous films they had made, which is another great way to search. Here are some that I came across and really liked.
Unfortunately, this is all I have time to post today, but here is the Wiki reference page for Czech animators so you can do a little research yourself on the Czech animators out there.
