Animation of data collection

This animation shows 20 degrees of data collection. It may load slowly, but once it has loaded it should continue to cycle, pausing briefly at the end before starting again.

Notice the zero level circle intersecting the direct beam position, which starts off just below the direct beam. This corresponds to a plane of spots in reciprocal space that passes through the origin of reciprocal space. As the crystal rotates, this plane becomes perpendicular to the X-ray beam and intersects the Ewald sphere only at the direct beam position, so it disappears momentarily.
