If you're reading this story on a Widows PC (Vista or later), do me a favor. Minimize your browser and any other windows so that just the desktop is showing. Hold down the control button. Then scroll your mouse wheel up about a dozen times. Congratulations, you've just replicated the effect of Giganticon without even installing the app.
Giganticon has one purpose, and one purpose only: it makes the app icons on your homescreen enormous.
