We made Looking Glass (LG3D) Live-Installer on KNOPPIX 4.0.2 using stable UNIONFS.

LG3D requires a video card which supports OpenGL. So the installer is effective on a machine which has nVIDIA GeForce card.
We exhibit the KNOPPIX with LG3D at JavaOne Tokyo. We could show it to LG3D developers.

If your machine has a GeForce card, please try!
