I forgot an excellent free app provided by Acme Brick Co.  The Acme Brick Masonry Designer lets you design realistic brick designs using dozens of different colors of brick and mortar. There are several brick and block designs and you can use different course designs. You can mix different colors and blocks together to make special designs. Anyone interested in architecture might find this cool little app very useful. When you are done making your design you can save it as a bitmap and a matching bump is also generated. Highly recommended!
