Flow??? Just wanna play with it....but I can't make this work

Just trying flow. Saw the wood carving example and figured I'd try it with
a blocky pattern for fun.

I can't make it work like the guy that created the carving.

The wording that flow uses seems terribly confusing. :(

Didn't have any problem following the slab test you posted earlier though.
