I always want to make the smallest computer, I wanted the "Gamebuino" that was around a few years ago. Unfortunately I found out about it after it's been out of production it seems. This seems like it should be similar in some respects and better in others. I haven't actually been able to take much time to test it much but I've looked through the documentation, which is pretty extensive. The creator also checked in on everything, which was pretty cool! :-)

Thank you Tim for your kind review!
I am glad you are so pleased. I always had the same problem - by the time I saw a video shield I wanted to use, it went off the market. So I made my own!
Be sure to check out github.com/NuclearManD/NTIOS_2.0 . It is an Arduino OS written for Arduino + Arduino Desktop Shield. You may find looking through it useful for your project.
Thank you again, ~ Dylan Brophy
