3D fruit fly embryonic development

“This video shows a fruit fly embryo from when it was about two-and-a-half hours old until it walked away from the microscope as a larva, 20 hours later,” says Lars Hufnagel, from the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany. The new microscope, knwon as MuVi-SPIM (for "multi-view selective plane illumination microscopy") enables rapid imaging of biological processes with an unprecedented level of detail.
