Animation Tool for 8x8 LED Matrix

I made this after attending a workshop at a conference. The Arduino and Gemma Mini Space Invader Wearable workshop at SoOnCon by Eric Boyd.
The default animation is fun. Once you get to the point where you get the sample animation to work it is not very difficult to make new ones. This form makes it even easier.

Requires browser to allow Javascript
Animation can have a maximum of 320 frames (estimate?). Each frame can be 2.55 seconds long.
I use this code to replace the file anim.h. I have tested it.

Click on a cell in the table to toggle it on or off. Click the add button when you are are finished a frame. Look in the output box for the code.
For example hit add a couple of times and then done, then reset.
To fill a frame with a letter click on a letter button.
