2. Weather forecaster/news/football scores. This one involves using RSS feeds to display the latest news/forecast/result or to whatever you want to show. Don't dorget you could program it with a Twitter api to show your tweets or follow a hashtag http://smstextblog.blogspot.co.uk/2013/12/raspberry-pi-lcd-weather-station.html
