The Letter F

I wouldn’t say that I’m particularly close to the letter ‘F’.  It’s no where in my name or that of any close relatives.  I suppose it has a connotation with failure, but since this project dealt with motion I thought about ‘fast’.  My objective was to implement something like the Roadrunner coming to a stop.  I feel like the final result matched up pretty well with what I had in mind.

anitypeSketchI was pretty frustrated with this assignment at first.  I’m not familiar with Javascript and felt like even doing a fairly simple thing was not working out. This letter ‘K’ example was the first that I found an example of the ‘complete’ parameter for the addTween function.  This would have been really helpful in the documentation.
