Every human brain is covered with folds, much like a fingerprint: each with its own unique pattern. In dementia, this pattern changes, but for two similar diseases, Alzheimer's and dementia with Lewy bodies, the changes are nearly indistinguishable to the eye. Doctors need a reliable way to separate them, because the treatments differ.

Three-dimensional worlds are made of millions of semi-transparent specks, like a giant tapestry woven from glowing droplets. Transmitting such a canvas usually takes ages and a beefy data pipe. SpeedyGS squeezes it into a tiny file, and it unfurls in a flash, like yanking a drawstring from a pouch.
