designer jinha lee wondered what was possible if pixels escaped from the monitor and became physical
objects, so he created bloxels. these small devices are a prototype for a new type of display system that
lee began working on while studying at the university of tokyo. the design uses a module-based
approach, consisting of translucent cubes that emit a colorful glow according to the transmitted data
from the neighbouring bloxels. the user can freely move the blocks around and the image will transform
accordingly. lee envisions using the system for multimedia artworks or as an educational toy. you can see
a demonstration of bloxels in action in a video on lee's website.
