Hele-Shaw Cell - viscous fingering from Nervous System on Vimeo.

2 x 8" by 10" piece of glass
8 x glass cover slips (for creating a space between the panes)
2 x syringes
1/4" tubing
glycerol
water + food coloring

you do always need to ask WHY though...How could this visula response to cell growth address the issue of visualising the unseen? could this idea relate to people visualising their own experiences ?
unusual celluar growth like cancer? long term health care issues arising from this?
