Few hours ago Fished adding transparency support to the canvas view I'm using . to it to work it needs kwin to run with composition turned on or some thing like compiz running . here is a ogg video http://upload.ruphy.org/raptortrans2.ogg showing the widget in grid mode
And a screenshot to make it complete.
