inkscanner

This project started out as the Milkscanner (as described on instructables). The basic idea behind this process is that you can capture the silhouette of an object easily when it is surrounded by a high contrast fluid, such as milk or ink.
When lowering the object into the fluid, the silhouette changes gradually, as the fluid obstructs more and more of the objects shape. By capturing the silhouette of an object at different stages of submersion, one can generate slices, that, if properly stacked together, can be interpreted as 3D data.

Here's a documentation video of a recent inkscanning performance:
