Because it was not always easy to find good-looking and scientifically correct images for publications and presentations, Luk Cox and Idoya Lahortiga from the Jan Cools Lab decided to learn how to draw 3D images. Now, in their spare time, they run somersault18:24, a company dedicated to producing scientific illustrations of molecules, cells, and viruses. They work for scientists, biotech companies, and science adepts who just love beautiful scientific images. The beautiful image of the nasty rotavirus below is from their hand.
