Have you ever wanted to build slanted engines, like on RaibenEFSF's Argus or Arcana http://www.youtube.com/user/00Raiben/feed (his channel) and have you been infuriated that you cant have wedges for ice crystals and lave, well I know I have!!! Then this is the feature for you. It has already been implemented into the Immersive blocks mod (as seen bellow) this is stable and working and i suggest that Schema implements this mod completely into the game as it has great ideas and is stable.
