Plinth Pedestals and Heluzz Tiles
You know how you can have a lot of trouble trying to put the Crystal Portals on top anything and have them still work? They seem to work well on top the plinths. And through the wall too. They're not perfectly centered but not bad.
Being able to turn the Heluzz Tile artwork in 4 dif directions is big on my wish list for deco purposes. And should probably be moved to the top of the Dev's priority list.
