Insufficient Funds Error

Here's a prototype I built to test an error state I was playing around with when working on the Rubicoin iOS app. When choosing an amount a user could run into a scenario where they have insufficient funds to make the purchase. To combat this, and make topping up easier I experimented with animating the main CTA, making it red and changing it's function. Ended up opting against it in the end as it seemed a bit gratuitous at the time, but an interesting exploration nonetheless.
