If you are a fan of Groovy, or even just curious what the fuss is about, there's a new resource for you: Groovy Casts. Groovy Casts is a blog by my good friend Merlyn Albery-Speyer containing short (five minute or less) screen casts about using Groovy, or about interesting and useful Groovy tools and libraries.
Some of the screen casts are done by Merlyn, others are simply collected by him from all over the web. Check it out!
