Introduced in 2003, Pixel Blocks construction sets consist of small translucent bricks shaped to stack top to bottom and grooved to attach side to side. These tiny pieces (less than a half inch high) resemble pixels, the tiny dots that make up the images on a computer screen. PixelBlocks can be assembled as two-dimensional designs and as three-dimensional models. The blocks come in 20 different colors encouraging immense variation in composition and infinite diversity in construction. Pixel Blocks Inc. offers an online Digital Stained Glass Creator that show how to turn any photo or artwork into a Pixel Blocks creation. Other web sites offer a showcase of individually designed Pixal Blocks creations. The translucence of the blocks make the most of building models on a light box This set probably appeals to most kids and adults who enjoy construction toys such as LEGO sets and Mega Bloks. But experienced gamers and individuals who like working with color and appreciate the pixel technology of graphics seemed to find building with Pixel Blocks particularly engaging.
