// here's a rewrite of the amelie.js to avoid global variables and eval via setTimeout(string..

@phiggins42: Even when it's called from inside an anonymous function? Also note that in this case it’s not exactly var str = dir = 0; but str = dir = 0 — the variables str and dir have already been declared.

@math - you are totally right. I thought the gist has changed since your initial comment and the 0's were in the var declaration for str && dir ... /me stands corrected.
