We've combined a fairly simple set of graphics operations with a set of appropriate art assets to make a working game more visually interesting. Visual appeal is a major part of a game's appeal on any platform and a large part of what will set an independent game apart from other games created by hobbyists. If you're using Corona as a tool for studio development (and even some professional studios like Electronic Arts are beginning to use Corona for mobile development) then techniques like these will make it easier to create the sorts of visuals expected of professional developers on a device of limited power using a straightforward framework.

If you're planning development for a Corona project, keep in mind that good visual effects are likely to require a little more work from artists, and a little less from programmers, because of the emphasis on creating masks and other images to support effects, rather than using code to dynamically create moving images and effects.
