Gamer Gridz, 3D clear platforms for miniatures gaming, is up on Kickstarter and looking to get funded.
From the campaign:
The idea for Gamer Gridz was slowly born out of many failed methods to represent vertical movement in my own tabletop games. Many of these attempts were overly complicated, or simply did not provide the desired effect. We began to think that nothing would improve upon the age old method of simply placing dice beside miniatures to represent how high they are off the table.
