I work on various open-source learnable programming projects and would like to make myself available to provide support for your lesson plans involving choc. aaron [at] kumavis.me
I'm currently having my mind blown by Bret Victor's "Learnable Programming", but after that I'll send you guys the details of how my class has been working so far.
Also, I started learning Clojure and Clojurescript about a month ago, but I'd love to try my hand at building something nontrivial with them.
