Shaded clock widget

This is my attempt to draw a eye-candy clock using cairo and conky.
I draw some examples on the picture with the parameters used.
Effects are nice but code need to be optimized.

Edit : I updated my "shadowed clock" to a "clock shaded", (is this more english ?). It's now easy to use because it's a widget that can be cut/paste in a Lua script.
Again, it can be downloaded from ubuntu forums .
