AWOL:
Looks interesting, vaguelyoccam
-like.
Yes, on the one hand both have this idea of parallelism and communication among processes (trails in Céu).
On the other hand, being derived from CSP, occam's processes execute very differently from Céu's trails.
I believe the synchronous semantics of Céu (a la Esterel) is more appropriate for Arduino applications.
