Alejandro from Colombia sent in these pictures that are circulating via email with the subject "Huevos Fantasticos" (or "Fantastic Eggs" in English). He asks, "Are these things real?" Well, I'm pretty sure they are real. I think they're examples of carved ostrich eggs. Do a google image search for "carved ostrich egg" and you'll come up with plenty of other examples. However, I don't know who the artist is responsible for these specific carvings.
