Financial Seismograph

Based on your control and data ripped from live stock trades the financial seismograph is meant to disorient and remind the user of the fragile nature of their financial system by allowing them to control the chaotic state of their world’s digital representation.

(The live data doesn’t work yet, but it will soon…)
