The ProblemOne thousand years ago, superstition and the sword ruled. It was a time of darkness. It was a world of fear. It was the age of gargoyles, avatars and mighty statues who protected the locals from evil spirits and nat-brain no-gooders.

The History of Door GreetersGargoyles:Gargoyles are a race of very powerful winged beings who were the defenders of castles. By day, they are immobilized in stone as statues on the castle parapets.
When the sun sets, the stone turns to flesh and they take to their task of defending their home.

The Door Greeter Critter
Design
An important Build-It-Yourself trick … Build the parts of your solution first. If you glue them all together as you go along, your model will be rigid. It will be difficult to make it move in interesting ways and it will be difficult to modify or fix.

Eyes and Face
Start by drawing some BIG eyes.
The eyes are very important! They can tell a lot about the soul of your critter. Many artists will often exaggerate the size of eyes. One measure of the quality of a photograph is how well the photographer has focused on the eyes.

The Structure
It is very important to build a strong structure. Think about keeping the heavy parts as low to the ground as possible so your model won’t tip over.

Mechanisms
Most Build-It-Yourself models are driven by a sidewinder gear train. This gear train enables you to control the speed and strength required to make your model move.
