Not sure I understand your equation, but I think you're right. It's a happy photo if you GRIN IN IT. The goal was to have a name that's easy to say, short, and bring a smile (Grin). We actually had a list of 50+ names which we brought down to four contenders and checked in every language using Google Translate; we those put out to a survey. 58% of respondents preferred Grinnit.
