The Everblock system brings Legos up to human scale and makes you feel like the mini figure. The system allows you to build wall, divider structures or tables out of the blocks. The bricks are available in three different size (and 15 colors) plus a 2 x 4 finishing cap to create a clean flat surface for shelving or tabletops.
The on-line store even has a virtual block builder so you can see what parts are needed (and change the colors) to figure out just what you want before you purchase. The contact us button also mentions that they are open to rentals.
You can even add effects to make these blocks glow with backlighting. Looks like a great new element to add to the event and exhibit design arsenal.
