The latest [release](http://www.thinkingrock.com.au/gamma20.php) of
ThinkingRock has been officially made only for Mac, but I copied the
application directory ThinkingRock2.app to my Linux machine, ran the
ThinkingRock2.app/Contents/Resources/ThinkingRock/bin/thinkingrock
shell script, and it seems to work fine!
