Modular gaming scenery

Regular green painted gaming boards that are decorated with out of place hills and rivers tiled awkwardly over the landscape have never sat well with me. Neither has the idea of having a fixed and unchangeable scenic board. The last thing I want to do is hand over £175 worth of my hard to come by cash to games workshop (I'm not suggesting that they are not deserving of my money, but it's rather a sizeable sum to be giving to anyone for a gaming board).

Begin project "Warhammer modular gaming board".

A big sheet of MDF gets you change from a £20 at b&q, and the best part is that they will cut it up for you!
This weekend I shall be making a trip to pick up a sheet and have it cut into 12"x12" blocks. This will be more than enough for my gaming board needs.

I decided to start with a 4'x5' map and designed the tiles on paper.

As you can see there are plenty options for layouts.

My main concern is that the tiles get knocked and the scenery scattered.
Magnets. I LOVE magnets. Rare earth magnets are my most favorite toy in the world. I plan to embed 6mm x 3mm ones
 into the edges of the boards - 8 per board - alternating the polarity so the boards can be rotated 360 degrees and will snap together.


I'm going to need 200 magnets all together but that will set me back about the same cost as the MDF, so I'm going to consider some alternatives...
