Back 2 Basix, an Australian based company, has just released the battle frame 5000 range for sale through their web site.
Basically, it is a set of magnetically connecting board segments, each 1sq ft and 33mm high. They can be assembled in a modular sense and the expansions enable multiple height levels to be created (i.e. mountains and valleys). It rivals the citadel realms of battle boards, but it comes "naked" -- meaning you will have to dress the surfaces of the battle frames to create a board. In terms of playability, it looks ideal for a cities of death board that could be endlessly re-arranged.
A video of the system is available on You Tube for viewing and evaluation. What do other people think? I am a little bit tempted to be honest!
