Ink Calendar by Oscar Diaz

Just saw this on Dezeen, I like the idea of using simple physics of ink spreading as a time based calender, although I dont really know how to control the speed of spreading that makes it accurate. it reminds Shin's project, one of my colleagues in UCL, he uses  diatoms to grow architectural facade, and its indeed fascinating.

maybe some similar idea is possible, the growing machanism as a time device.
