This is a less known open source portable app to control all the LEDs in your mouse, keyboard, PC etc. -- basically just wanted to give folks a heads up that it exists.
I use it probably Not as intended... the PC on my desk has a glass door, and 2 sticks of RAM with LED strips across the top, showing a motion effect by default. Not a big deal, I could live with it, but the motion effect goes out of sync between the 2 sticks, which I absolutely cannot tolerate. It drives me loony[ier]. SO I have the app start with Windows & load a profile turning the lights off.
