Abstract
A device, system, and method for utilizing precisely patterned and chemically loaded three-dimensional porous containers akin to 'chemical voxels' is disclosed to enable display of dynamic visual patterns via spatial and temporal control of both local and global chemical release. Variations in porosity, volume, shape and relative positioning of the chemical voxels can be used to control the types of images that are formed with control in both space and time. Static or moving images can be displayed using the device, system, and method of the present invention.
