In the past I have used Kawa and SISC Schemes a lot: good projects. However, Clojure has the momentum, community, etc.

I wrote a Scheme book for Springer-Verlag back in ancient history and I still use Gambit-C a reasonable amount and Racket is pretty cool also. So, I am not biased against Scheme, I am just saying that Clojure might be a better place to start if you want to experiment with Lisp languages on the JVM.

> Armed Bear Common Lisp ( www.armedbear.org/abcl.html) is a reasonably complete implementation of the Common Lisp standard, but it suffers from that the distribution can't be built unless you have another Common Lisp system installed, which may be a problem for beginners.

That's not true at all. ABCL can be built with Ant.

This article is like a time capsule from the pre-Clojure age.

OurDoings, http://ourdoings.com/ the photo site designed for your memories, is implemented in Kawa Scheme.

Yeah, ABCL is solid on the JVM. I am still struggling to get it on Android though.
