Hi Eduardo,

Thanks for the video.  It made me smile!

I'm glad you like the SignWriting Thin viewer.  It requires a 
SignWriting Icon Server to provide the server side SVG images.  The 
server on Wikimedia Labs is probably the best server to use.

This is last years technology.  The new technology uses TrueType fonts 
and does not require server side SVG images.  This eliminates any visual 
delay and greatly reduces network communication.  For example, a large 
page of the ASL Wikipedia will require over 1 MB of images.  It will 
require only 30 KB of Formal SignWriting if the fonts are installed for 
the same page.

There are 2 fonts, available in the SignWriting 2010 Fonts project.

For Javascript programming, the SignWriting 2010 JavaScript library can 
easily transform FSW into either SVG or PNG.

The minified file is less than 20 KB and includes a lot of additional

Thanks for the inventive work.  I'm always surprised and excited by what 
you accomplish.
