This cool free plug-in from Auto FX gives you a wide range of mosaic artistic effects with endless possibilities. Mosaic makes your photos look as if they were created out of a mosaic tile. Photo-realistic depth and variable tile size and color options give this effect an infinite number of looks.
Mosaic is downloadable in both Windows and Mac formats. This plug-in is available for free but does require a serial number to activate.

This one is definitely a high quality plugin with numerous possibilities for artistic creations.

The sheer variety of options alone will quickly convince you that this is not your average mosaic tile effect.
