Meet the face of PFLUM FORM – an installation based on a modular typeface designed by Central Saint Martins students, Thorbjørn Ankerstjerne and Jonas Lund. Installed in a darkened room as part of their degree show, a series of white triangular modules are displayed to form a "face" and also the letters "R", "U", "O" and "K" when coloured light is projected onto them. It's a mesmerising effect.

As the projection is closely adjusted to hit only the triangles, it gives the impression that the light is actually part of the surface. Synched up to a soundtrack, the modules are illuminated in a range projected colours and a robotic voice intones variations on "R.U.O.K" (flashing the letters up as it does so) until the entire face becomes animated – at one point revealing some fangs and a long red tongue.

Up close the triangular modules are simply blocks of white card

It's a beautiful combination of digital technology and old-school light trickery: and it'll look great at ten times the size on a dimly lit stage.

Here's how the complete typeface looks as a series of 3D forms:
