hi - a favour required immediately

hi i need a plugin module in javascript , which the plugin should be similar to that of igoogle gadgets.
Instead of JS, the plugin can also be in jquery/codeigniter. Ur inputs on this would help me a lot in my immediate requirement, if u could send my the plugin name or url links.

Thanks,
Usha

It would be kind of cool if there was a version of this for ruby or jruby.

Just as an alternative to rails.
