I got some new tiles.

a friend send me a package of some tiles,

look, we have about 60 colors

I use a digital camera to sample them, import it into Easy Mosaic tile lib. and try created a mosaic:

nice tile mosaic, right?

another nice try

The new tiles work perfect,  And they are really cheap.
Each tile is 10mm x 10mm, the price I got is 12 Euro for 1Kilogram, about 980 to 1000 tiles.
