[...] What kind of Dungeon terrain are you plannign to sue with them?
Lot of :
1 - Caverns (slaps without doors)
2 - Dungeon classical Corridor (slaps with doors)
3 - Woods from Mystery Forest (slaps without doors too but woody)
4 - Swamp from deadly marsh (little islands path on mud )
5 - Iceland of the frozen lac (little frozen islands path on cold watter)
6 - glowing embers of the fire mountain (little tectonics plates on hot lava)
7 - ... certainly more in my plans but less in reality

all slaps/little islands will be make with Depron (cheap material : polystyrene without hole for walls isulation)
I plan to make a post soon about these "dungeon slaps". but you could see some of them on
my blog Stéphane
