It makes for a good demo I suppose, but I prefer React in a couple places: there's no separate template, style construction is done with an object and not a string (constructing that style string for HTMLBars seems error prone), and the connection between the values on the Ember object and how they will be used in the DOM is guessed only by naming convention. You could use `this.set('hotdogs', count % 255)` and reference 'hotdogs' in your template in place of 'color'.
