It's actually similar to Latte Dinamico: https://www.opendesktop.org/p/1208850/
The layout contains installed widgets "Event Calendar", "Media Player Compact" and "Show Desktop (Win7)".
You can find the wallpaper here: https://www.opendesktop.org/p/1243039/

The shadow that you see at the bottom is actually drawn on the wallpaper with GIMP. I would like to have this type of shadow from Latte, but it is not possible unfortunately, not that i know about it.
