Part of the OnTime Group Calendar Notes 2011 client is the option to only display favorite groups instead of all public groups. To switch between the two views I wrote a small animated accordion control. Nicely animated and double-buffered. Loving it!

SWT animation is a pain to execute on, but extremely fulfilling when you get it right.
I like it… would be curious to see how well a vertical implementation behaves.
