JLipSync is a Java program for creating lip sync timesheets/x-sheets/exposure sheets for traditional or 3D animation.
Simple program, very similar to old versions of Magpie. JLipSync hasn't been updated in a very long time, but it seems to work great if you download the correct package. The "jLipSync_0.9_complete.jar" download that is currently linked to on the main page does not work, but I downloaded "JLipSync0_9_source.zip" from Files/JLipSync Source/JLipSync 0.9 and I was able to run it without problems by double-clicking on JLipSync.jar. Seems to work on both Mac OS X and Windows.
