An anonymous reader writes "The University of Groningen, in the Netherlands, has converted a 3D theater into the world's largest touchscreen, used for teaching mathematics and computer science students interactivity. The screen has a curvature of 135 degrees and is transparent."
"Conversion, fastidious Goddess, loves blood better than brick, and feasts
most subtly on the human will."
-- Virginia Woolf, "Mrs. Dalloway"
