Don't know if it was mentioned before as this project appears to be more than a year old, but I just happened upon this by following the link from this youtube video collection (has several LFS examples together with some flight sim stuff) - the maker claims that it don't cost more than 500 euro to make this 2DOF motion cage (can't call it a platform really). Apparently it's based in the designs of an older flightsim motion cockpit. The use of PVC pipes as construction material is quite interesting.
