This was a simple semi-transparent skin I have made for the default Screenlets Calc.The pink part of the screenshot is my wallpaper.Installation: open the Screenlets manager, select the Calc and click on "Install New Theme", on the panel at the left. Choose the "clear_calc.tar.gz" file. Then, restart the calculator and it may work.
