To play wigh this, you should download this repo and place the files in the repl_sessions directory:
https://github.com/lambdaisland/witchcraft-workshop
You'll need to load the figlet-writing namespace in the REPL before you load any namespace using it. (I don't know how to get the writer on the classpath in this project.)
I found the FigFonts here: https://github.com/xero/figlet-fonts/
