Love this app

The best winter app I have - absolutely love it. Agreeing with some other posts, it takes about 10% CPU on my 3 year old MBP and WindowServer takes much more. The fan does run constantly, but considering the aesthetics it adds to the computer and winter in general, it’s a very worthwhile trade-off.
Two requests for future - allow more snow pile-up and allow user to select which screens to be operative - my emails could use some snow.
You can’t beat this app for inexpensive winter enjoyment!
