Dramatic re-enactment

I've obtained permission from Ursula and Imogene (yes, pseudonyms) to post the following shot of them tossing the icosahedron about in a dramatization of our in-class activity yesterday. (In which Imogene actually took part!) Note the icosahedron itself, just leaving Ursula's hand, dark against the white wall behind. (I shoulda been an SI photographer...)
