thnx very much for that usefull info! i've thought of something like that as well. But this is on an alien planet, this "oracle" if ya want, is not visited for a long time. The wall will be rusty, the floor will be slimy, the hologram will have some failures (like: some pieces missing from the face), the lights will be dimmed, the atmosphere will be smelly. A real mood-maker ^^ CZ
