is a virtual building toy that simulates building blocks that can be stacked and grouped in an infinite number of ways. Over 300 colorful blocks organized into 10 block sets allows for endless building possibilities. There are blocks to build houses, mechanical parts, structures, pulleys, axles, wheels, and much more.
Simply select any block from the box and move and rotate it into position. You can add text, and choose a background image or a colored background (solid or gradient).
When you are finished you can save and print your models in color. You can even use your model as wallpaper on your desktop or export it as a bitmap image for use in a paint program.
Many example models are included, ready to be loaded and modified, ranging from simple trucks suitable for small children to complex and highly detailed machines.
