In this October, Bitcoin's price is on fire. It increased $1,601 since Sep and $4,859 since the Sep of 2016. Despite of the overall rising trend, Bitcoin's price fluctuates a lot within each week, which makes buyers and sellers hard to decide when to exchange. The alternative of Bitcoin, Ethereum, fluctuates too but the overall price stays rather low.
I created a torusKnot using Three.js to reflect the mood swing of buyers within recent weeks. The number of geometry winds of the torusKnot is proportional to the price change from within the week.
