From the announcement:
Encounter Elements is pleased to announce the release of their first product, The Encounter Bricks Construction System, a modular tabletop gaming terrain built with the RPG'er in mind. We were tired of flat battlegrounds, and we were tired of the super expensive 3D terrain options that are available, so we built our own and this is the finished product. We call it a Construction System because we think that you shouldn't be limited in what you're able to create for your RPG adventures. Creativity, Versatility, and Affordability; those are the key elements that we based our product on, and we think you'll understand why after you try out The Encounter Bricks Construction System!
