We've just released the latest KidsRuby version 1.3, and we're very excited to announce built-in support for the Sphero robotic ball from Orbotix (http://gosphero.com/). If you were at RubyConf in Denver you might have seen the preview, and now we've got everything you need to get started learning about the wonderful world of robotics! Support for more robots coming soon...
In addition, we now have the standalone KidsRuby Installer for Raspberry Pi (Raspbian), and KidsRuby Installer for Debian, including Ubuntu and other Debian-based Linux versions. Get them while they're hot from our download page at http://kidsruby.com/download.html.
