Growth Modeling of an Onion

Here’s a bit of robotic kinetic art that might interest you. David Bowen is an artist. His web site called david bowen kinetic, robotic, interactive and sculptural works shows a device he calls a Growth Modeling Device. Here's his description:

This system uses lasers to scan an onion plant from one of three angles. As the plant is scanned a fuse deposition modeler in real-time creates a plastic model based on the information collected. The device repeats this process every twenty-four hours scanning from a different angle. After a new model is produced the system advances a conveyor approximately 17 inches so the cycle can repeat. The result is a series of plastic models illustrating the growth of the plant from three different angles.

There is a video on his site. It’s pretty interesting.
