Glimmer: Visual jQuery Design Tool

Glimmer is a free interactive design tool to create jQuery effects and interactivity for your web pages.

The installer for Glimmer can be downloaded from http://code.msdn.microsoft.com/glimmer/Release/ProjectReleases.aspx?ReleaseId=2578

Glimmer offers a few options for applying jQuery effects. You can use one of the wizards like image sequencer, drop-down, etc or open up an existing file and apply custom jQuery actions from scratch.

Official Glimmer samples can be downloaded from http://mschannel9.vo.msecnd.net/o9/mix/labs/glimmer/glimmersamples.zip

I found this tool thanks to this post http://www.techsutram.com/2009/03/glimmer-jquery-designer.html
