Introduction

Many types of objects can be put in the Eggbot and plotted on. In choosing an object, a number of questions come into play:

Size - How does it fit and what adjustments do you need to make to the Eggbot to draw on it?
Surface - What are you plotting on? Eggs, glass, ping-pong balls, etc. all have very different surface textures and ink absorption.
Expense - Are you doing ultra-fine, archiveable work or rapid-fire demo's?

Types of objects

Chicken eggs - the default standard. Inexpensive, absorbs ink well. Also fragile. Tips on Blowing Eggs.
Duck eggs - bigger than chicken eggs, and narrower proportionally.
Christmas ornaments
Ping pong balls
"Ball pen" balls
Golf balls
Lacrosse balls
Plastic eggs
pumpkins
Wooden balls/eggs
ceramic eggs from Hobby Lobby
Acrylic Spheres[1] from CorSec Engineering[2][dead link] - marketed as planet kits but fit in an Egg-bot and comes with a stand
Decorative glass balls, for example the 4" spheres from CB2
Wine glasses - some wine glasses (generally with relatively short stems) can fit with the tailstock all the way back. You can use a disc or jar lid to hold the open end of the wine glass. Tape it to the wine glass or use a rubber gasket to hold it in place. The stemless Reidel "O" tumblers are likely a good choice as well.
