You are welcome in the last version of the lambdaway project: http://lambdaway.free.fr/lambdawalks/

All these pages are blank without JS, which is totally understandable, but, is there an About page or README somewhere just to give the gist first?

Sorry this site is a wiki and can only work with Javascript enabled. And the first page gives all the necessary explanations as well as a series of links to more detailed pages. As far as I know it does not contain any malicious code.
