Plan 9 Acme Inspired Editor, done in Scala.
The Downloads section has distribution bundles built using the latest code and Scala 2.9.2 and Java 1.6.
In Ubuntu, here is a script I use to run the editor using the download bundle.
#!/bin/sh
Z_PATH=$HOME/z
java -cp $Z_PATH -jar $Z_PATH/z.jar $*
How to use it is documented in the Z Help Screen.
