# Using Mathematica to decorate Easter Eggs

• Discuss this post in our forums

I’ve been using Mathematica since just before the 2.0 release, and have recently switched to Sage. Haven’t given it a real killer workout yet, but everything I’ve tried, it has done, and done well. It includes some fairly extensive graphics support, so Easter eggs shouldn’t be a problem.

Sage is open source under GPL 2 and written in Python. It incorporates a lot of excellent scientific code already available in Python (Numpy, Scipy, etc.) with the advantage of a uniform interface. It seems to be reaching critical mass in the community, and it has the huge advantage over Mathematica et al that you can get at the code and see exactly what it is doing.

Definitely worth a look.

This is deee-lightful! My kids spend so much time on the computer…this is a good way for them to partake in the wonderful Easter holiday without having to leave the constrants of their computers – great!

Very resourceful page, on egg shapes.

gee i hope you are also letting them enjoy real world egg dying as well….

You do realize, of course, that gold leaf-encrust on real eggs would be much, much cheaper.

You are paying HP approximately $4,500 per gallon for that printer ink.

um, disconnect, go OUTSIDE and color and hide some eggs. work on you tan a little.

The tradition of computer-generated Easter eggs dates back over three decades.

Cory, don’t use Mathematica, use Sage (free and open source)! It can paint eggs too:

Hamptonio, it’s Kathryn Cramer who’s doing it, not Cory.

Regarding whether I let the kids touch Real Eggs, you can see our Paas-dyed eggs in Flickr. Phineas & Furb were a popular theme, as were portrait eggs. We worked on the Mathematica eggs while the chicken eggs were in the dye bath.
