This is a simple ticker that pulls in the price of a Bitcoin and displays the price in a variety of currencies. The prices are pulled from either Bitstamp or BTC-e, and are updated every 10 seconds. Exchange rates are pulled from www.getexchangerates.com. Vector graphics were pulled from a forgotten public resource, but are much appreciated.
This can be seen in action at: https://extant.digital/TickerWidget
DEPLOYMENT: Simply deploy the package to any PHP server and run. No API keys are required.
