Scientific Animations. Colourful, clear, and easy to understand. They range from carefully constructed virus models to mathematical ideas. From black holes colliding to impossible lenses that change shape and refractive index. From fertilization to Ebola. From diesel to Doppler to DNA. From flu to fibre optics. From sperm to sine waves. Perfect for school teachers and university lecturers with academic licences for individuals or entire campuses. Great for a museum display or TV news. If colour's not your thing, our sepia versions offer a subdued, authoritative, and antique look.
