I dare to say my Quinto with Etoys in six lines of code in Etoys is  
simpler than the SBE-version.

The trick is to make the layout so that neighboring cells overlap each  
other a bit.
Then make the corners of the cells rounded so that diagonal neighbors  
do not overlap.

BUT: for using my or the SBE version one still needs to install sth.  
first -- even if it's Squeak... ;-)
Not so if you used JavaScript:

(Official name for Quinto seems to be "Lights out", but everyone seems  
to have his or her own version...
http://en.wikipedia.org/wiki/Lights_Out_(video_game) )

Dan Ingalls and other great folks bring the power of tile scripting  
and visual composition to "No-Install"-JavaScript with "lively kernel".
(google for lively sun / I am cross-posting to their list)

Their "lights out" will turn some lights on. Or will it be you who  
does it?

Cheers
