I've created a few Roku channels which you can add to your Roku box. Here's what I've created so far:
Candy Bear - 60 levels of tasty arcade fun.
Four In A Row - classic game of skill.
Photo Puzzle - classic sliding piece photo puzzle.
Kevin's Hiking Photos - all the images from my vast hiking web site, on your big-screen TV.
Kevin's Chess Videos - access to several chess tutorial videos, mostly for kids and beginning players.
