Last week Holi was celebrated in India (with a lot of colours) and this week Easter in the Christian world (with equally many colours). Happy celebrations! Easter eggs are very popular within the IMAGINARY team, not the chocolate ones, but the ones you hide within a software program. We hid two Easter eggs in our museum exhibits: one in the MiMa museum in Oberwolfach and one in the MoMath museum in New York. They are tricky to find and generally open new parts of the program or offer special objects to play with. A small hint: a special sequence while selecting surfaces at the Formula Morph will give you access to the Easter egg in New York. And in Oberwolfach try to find a secret spot at the Cinderella exhibit (on the lower left side)… Let us know if you found them!
In the image you see a simple egg equation defining all points of the surface of an egg. It is just a squeezed sphere, where the parameter a defines the level of “eggness” (if a is 1 it is a sphere).
