Here's a nice little Stack from a new Stacks Developer - Aaron Marquez - over at StackManiac. GrayScale allows you to add an image to the Stack and apply a transition that renders the image, upon hover, to go from black and white to color or you can choose for the image to go from color to black and white. The Stack is very easy to use. The HUD is short and simple. So join me as I review one of StackManiac's first releases. Less
