Perhaps not such a coincidence.  Part of my background motivation for  
Curly Logo was accessibility.  That led me to think that using *  
and / instead of × and ÷ was a barrier to understanding: before using  
almost any computer programming language we have to explain that *  
denotes multiplication and / denotes division, it's just an  
unnecessary hurdle.  Of course my keyboard doesn't have × and ÷  
keys.  I'm sure similar thoughts occurred to the designers of OLPC.
