Pixelate let's you make your own zoomed-in, blurred out, pixelated games.
Add in all the images you want. You can also add an answer to reveal with the image. Next, set the images effect mode. Customize it even further by giving the file a background.
To play, pick the image you want to show and then increment the effect. Or, reveal it all at once!
Pixelate - No Photoshop skills required.
