    There’s nothing dull about seeing a spectrograph working.

    Edit: also, how come you can’t find a real hologram displayed in a museum?

          Don’t expose it to UV or excessive heat.

          Also, the process is somewhat reversible: Retrobright

            Yeah retrobright is… Basically only a reasonable option if you want things to look good for gathering footage, it’ll go back to looking like shit within a year or two.

        But seriously, all of those have older versions that don’t work as well but look absolutely cool.
