Teletext is still alive in many parts of Europe. The Austrian broadcaster still has a service and they have an online interface for it: http://teletext.orf.at/
The Austrian broadcaster ORF even released an TELETEXT app (!) this year [1], available for Android [2] and iOS [3].
An then there is also art, as with every "old" tech. Check out the International Teletext Art Festival [4].
