How do you ringify a block with JavaScript?

gray ring is Snap*!*'s visual representation of what in text languages is called lambda (the Greek letter λ, which is what Church called it in the lambda calculus).

I have stumbled on "Lambda for dummies" at The Lambda Calculus for Absolute Dummies (like myself) - Joscha Bach which I find more accessible than the Wikipedia article. If you like it, you may want to add the link to the Faq post about the lambda, too.
