should we continue to focus on nuttx?

Hmmm... I did that too.

I'm not certain, but I don't think that this example is using any of the
 NuttX graphics facilities.  I am not sure what he is doing, but the 
fonts don't look familiar (NuttX supports 17 different  Helvetica and Times Roman 
fonts) and the drawing certainly does not come from Nuttx.  I don't have
 any good demos of the graphics from NuttX but they are all rendered as 
"3-D" images.  I've attached the output of the button array unit test to
 give you a better idea of what I mean.

(That attached PNG came from here: 
http://nuttx.svn.sourceforge.net/viewvc/nuttx/trunk/NxWidgets/UnitTests/CButtonArray/cbuttonarray.png?view=log)

This button array, by the way, can used with a touchscreen as an 
on-screen keyboard (with the output going to an edit box).  "Widgets" 
like this have already been used to implement the complete GUI for a 
medical device.
