Just a reminder... I'm doing a holography panel at Furthemore.
It will be on Saturday 6:30 pm to 8:30 pm.

Bring an interesting object about the size of your fist (holograms are
life-size), and we will walk you through arranging it in the holographic
apparatus, exposing a piece of film, and then developing that film to make a
white light viewable hologram of your object to take home and amaze your
friends with.

The fine print: This is approximately a high school physics lab, there will
be lasers, film, chemistry (not especially toxic, but it sure stains), and
darkness. I would not recommend it for very young children, or people in
fursuits.
