##The Script
Save this to a python file after customizing your Philip's Hue Bridge ip, username, and light_id.

from urllib import urlopen
import json
import time
from beautifulhue.api import Bridge

# CONFIGURE HERE
bridge = Bridge(device={'ip':'192.168.1.28'}, user={'name': 'newdeveloper'})
light_id = 1

while True:
    active_light = bridge.light.get({'which': light_id})
	previous_color = -1
	if active_light['resource']['state']['on']:
		weightedprices_url= "http://api.bitcoincharts.com/v1/weighted_prices.json"
		weightedprices = urlopen(weightedprices_url)
		weightedprices = json.loads(weightedprices.read())
		weighted_24 = float(weightedprices["USD"]["24h"])

		currentprices_url = "https://www.bitstamp.net/api/ticker/"
		currentprices = urlopen(currentprices_url)
		currentprices = json.loads(currentprices.read())
		currentprice = float(currentprices["last"])
		
		color = 0 # red
		if currentprice > weighted_24:
			color = 25500 # green
		if color != previous_color:
			bridge.light.update({'which': light_id, 'data': {'state': {'hue': color}}})
			previous_color = color
			print "updating light color -- current=%s, avg=%s" % (currentprice, weighted_24)
