A program for the Roku digital video player that shows you blinking lights on old computers. Makes a great screensaver!

This program isn't in the Roku Channel Store, so you'll have to install it on your (developer mode) Roku device. See the instructions in the roku subdirectory, it's pretty easy to do.

The program cycles through several light animations (random fast, random slow, binary counter, left-to-right). Adding new animations to the source code is pretty easy if you've ever written code before.

Light Panel HD doesn't use the network when it runs. All the images are packaged with the application.

Quick Install

If you're not interested in installing from source, Light Panel HD is available as a private channel.


Sorry SDTV viewers, Light Panel HD only works when your Roku is in the 16:9 display mode. See roku/ for the reasons why.

Light Panel HD requires a Roku 2, Roku XDS, or Roku XR (or presumably any newer generation), because the images make it too large to fit on a Roku 1 (which has a application size limit of 768,000 bytes).


It's really too bad you can't see the lights blinking in these images. You'll just have to install it to see it in action.
