Cool idea Hymn.
The only trouble I can really see is the transportability of the board. I might be able to get the design to be modular but the electronics might stuff it a bit.
You may be able to use the colloseum parts to hide the electrics, so the colloseum is detatchable but rests on top or similar.
Yes it's a little but early with SG7 not even a week gone but as per Reaper's request at the tournament and Brookesy's comment, here I go.
With a full year I have no excuses for not getting a pitch done this time!
My plan is to get a rockpool pitch complete with the following:
-string to outline the grid
-resin to create the watery effect (though it will only be shallow and only to a point that the visibility of the grid in unaffected)
-use mirrors on the floor of the pools to give the illusion of depth
-shells / sand / rock mix for the rest
-a team to suit
The only guide for me is that it has to be easy to use (eg grids must be easily visible, the pitch can't be too rough, no flaky bits) and easy to transport (a layer of foam and good to go is the idea). It will probably be in three pieces plus turn counters / etc.
And the ultimate yardstick
