Now Christmas is over, I'm missing my Unicorn Hat decoration. So how about a New Year countdown?
Using my Scrolling text library, I've knocked up some quick Python to display (in a random colour) the number of seconds remaining until 00:00:00 on Jan 1st 2015. Once that time is upon us it will display a suitable message.
from dateutil.relativedelta import relativedelta
from datetime import *
from UHScroll import *
cols = ['red','white','green','blue','cyan','yellow','orange']
t = relativedelta(NOW,NY)
total = (24 * 60 * 60 * t.days) + (60 * 60 * t.hours) + ( 60 * t.minutes) + t.seconds
countdown = str(total)
if total < 0:
time.sleep(0.2 * len(countdown[1:]))
unicorn_scroll('happy new year!',random.choice(cols),255,0.1)
