...In a block called tutorials, I think this could be an invaluable addition.
but...me likes the name supersonic ;-)
The idea is a very quick, "supersonic" tour of the most important things in Cocoon. Next step towards understanding is to take another slower, more complete tour of the parts that you want to study, but that's another story (and IMHO another block).
I wouldn't want many tutorials to be mixed in a single block: I think it is important for people to be able to look at the contents of the supersonic (or whatever it is called if the general consensus is to change the name) block and know that the files found there are all it takes to build the examples and the related presentation stuff. Makes it more modular and understandable.
I think the name is distinctive enough to stick. "Supersonic Tour" - just a small, standalone and understandable Cocoon application which shows the most important things. Once the word gets around that this is a good entry point for beginners, people won't have trouble finding it.
