Adore so much about this. I'm from the states so not at all familiar with ceefax, but now I'm fascinated to research more into it as a precursor to the 24h news cycle. The recreation of an 80s digital interface is on point, I'm hugely envious (I've done some projects trying to do something similar and this is just so slick).
What an amazing comment to receive out of the blue! I really appreciate that you enjoyed this little thing, and absolutely encourage you to look into Ceefax more. There's not a huge amount online about it but it was hugely influential and there hasn't really been anything like it since
