I just came across this:
http://www.brickforge.com/kickstarter/kickstarterhexibrix/
I regard this as quite a good idea! While I am going to wait for additional colors to come out, you might want to join this.
Here are some questions and remarks:
- Can someone show me a construction of hexibrix which has a horse on it? Does that work for mounted troops?
- A good additional idea I think would be a hexibrix which just has normal studs on it, but all over it. One could e.g. build a tree or rock on it and link it with others to make a plate for a regiment.
