Photo mosaics are pictures made from hundreds and thousands of tiny images. The small tile images can be seen close up, but at a distance, an entirely different image can be seen.

Robert Silvers is the creator of Photomosaic™ software technology. His company produces many of the famous photo mosaics you see in magazines, ads and posters today.

You can take just about any ordinary image and make a photo mosaic. Make sure you have a folder full of images, at least 100 or so, somewhere on your hard drive. These are the images you’ll use to build the photo mosaic. You may need more or less than 100 images for your mosaic but after you build one you can always add or remove images to get the best results.

Here are a few applications that you can use to make your own photo mosaic:

• MacOSaiS (Mac)
• MozoDojo (Mac)
• eMosaics (PC)
• Andrea Mosaic (PC)
