info appreciated

Hi, sorry to spam the list with this.

I am new to the list and have joined with a specific agenda. I am trying to
invent a very simple functional language for an entertainment software
product. Succinctly, it needs to be easily understandable by a machine,
easily learned by children as young as 6 and as non-ethnocentric as
possible. I am considering modeling it after ASL or something similar and
using a simple grammar like a context-free grammar. Does anyone know any
valuable info for this endeavor or anyone who has attempted this before?
