Can anyone recommend a Lisp dialect / environment which is suitable for web-based publication, and game multimedia (graphics, audio, control, etc.)?
LWJGL, jMonkeyEngine, libGDX are the three top Java game engines you could use with Clojure which have been used for real games.
There's also the Arcadia project, which lets you use Clojure instead of C# to script the Unity engine.
For JavaScript targets, you have Phaser, pixi.js and EaselJS as good options.
I'd recommend you go straight for interop with a Java or JavaScript game engine. The Clojure/Script wrappers are mostly immature, and don't add much benefit.
If your just interested in art, generative stuff, controllers, etc. You can look at Quil (processing for Clojure/Script) and OverTone (Clojure interface to supercollider)
With Lisp, I often end up in the weeds looking at tools and tech that may or may not still be supported. I have a hard time figuring out a well-established set of tools that'll get me a first-class playable game in Lisp.
If anything I'm going to watch this game jam just to see what everyone's using and how good the results look.
add opengl and you can do 3d games
I found an example of a game created in it: https://deque.blog/2017/03/28/building-a-clojurescript-game-... ( Source: https://github.com/QuentinDuval/triboard/tree/master/src/clj... ) Seems fitting that it focuses on AI.
ChickenScheme uses continuations to transpile to C. So it supports interfacing easily with C libraries, and it supports binary distribution (Which in my exprience is difficult in most lisps/schemes).
You can use it out of the box with something like SFML or whatever.
Potentially I could use Emscripten's HTML5 API ( https://kripken.github.io/emscripten-site/docs/api_reference... ). Although I was hoping for a nicer interface than calling out to a C translation of the JavaScript APIs.
