I actually did some preliminary work to make this possible.  I made a demo 
where text is painted by a Lua script and it animates “flying by” on the 
screen.   (http://grub.gibibit.com/files/gfxmenu-lua-1.iso.gz for a demo ISO.)

Besides making the GRUB video API accessible (partially, so far) to Lua, I 
also made Lua able to implement GUI components in the graphical menu 
interface.  This is limited at this point and only paint() and destroy() 
methods can be implemented in Lua.  However, I think being able to implement 
new GUI components in Lua would be really great.

If my code would be any help to you, I can send it to you.

Colin
