Graven Games has a review up of two spell effects sets from Mechanical Warhorse: the Elemental Fulcrum and Fireballs.
From the review:
Today’s review is full of destructive magic courtesy of Mechanical Warhorse, a company based in the US who produce a range of laser-cut acrylic gaming aids and terrain. The range inlcude items like wreckage markers and wound counters, but today we’ve chose to try out their Fireball set and Elemental Fulcrum (Air) terrain. One of the great things about this acrylic terrain is that it doesn’t need painting, so you can just assemble it and start playing right away.
