Easy ways to try out and test Lisp syntax?

Question

Clojure has introduced me to the concept of Lisp syntax, and I'm interested, but it's a pain to get the Clojure repl set up and use it on different machines. What other resources are there out there for actually on-the-fly testing and playing with Lisp syntax?

I'm imagining something like a website where you can input rudimentary code, or a browser add-on, or even just a standalone application that steps you through Lisp (something that runs on Linux/Ubuntu).

Haven't been able to find anything like that to start me off in a simple/accessible way.

Answer 1

At the risk of losing all of my rep points, try newlisp.

Answer 2

The SISC Online REPL is exactly what you need. It accepts Scheme syntax, which is a variant of Lisp.

For a standalone app I like PLT Scheme because it seems to work the same on every platform I've tried. I was previously using MIT Scheme on Ubuntu, but decided to switch when I bought a new machine with 64-bit Vista installed.
