Version 1.31 of the Meggy Jr RGB library for the Arduino development environment has just been released and posted; you can nab it here. This new library version is recommended as an upgrade for all users. It features several new example programs, including a scrolling message "readerboard" program, an updated version of the game Froggy Jr, and three example programs demonstrating serial communication between Meggy Jr and a host computer-- one of which is a binary clock. The Meggy Jr RGB programming guide (available on this page) has also been updated to reflect the new version.
