Can you recommend any free Forth video tutorials (except for following) ?
The only one I know of is Samuel A. Falvo's excellent "Over The Shoulder Episode 1: Text Preprocessing in Forth". MPEG. 102 MB.
There are also videos from the annual Forth Day, but I don't consider those to be tutorials.
(Unfortunately Forth is, like R, C, C++, Java, C#, D, COM, .NET, F# and Frontier, an unspecific search term. Search tip for Forth: qualify it with "ans" - as in ANS Forth, the ANSI Forth Standard.)
Accumulated based on answers and other information:
