You can see a few things on my blog: http://jlongster.com/. Recently I've been helping out with the sweet.js project (http://sweetjs.org/) to implement macros in JS. People really need to understand how macros transform a language. It's going really well so far.

I'm also working on the idea of live evaluation. Most devs are used to writing code and refreshing the page. There are tools that help with live evaluation, but they all suck. I am working on something that will give you a better connection with your code, and fully support the idea of incrementally coding up an app.

I'm not focusing on specific Lisp/Scheme features, but more about the philosophy behind them. Any project I do I try to expose the good stuff that I learned from Scheme.
