Took my first stab at creating a new effect for my outside LED strips. Nothing fancy, based originally on the Snake effect. All it does it start with all green LEDs, and then change them to red, one at a time across the strip. Pause when it hits all red, the starts changing to green in the same direction.
Could have been a lot more efficient, I am sure, and doesn't really use the parameters in the json file. But hey - it works, and looks good across the front of the house.
To install, just unzip and put both files in your "effects" directory.
Merry Christmas, all!
