The BBC's studio for covering the general election is as fancy as you'd expect.
It's even set up a huge map of the UK outside Broadcasting House showing all the constituencies.
How things have changed. Pictures from the BBC's election archive show that back in 1950, someone in a white coat had to PAINT the results on the wall.
The Tories were represented with white and Labour with black because a) this was before colour TV, and b) there weren't any other parties that mattered.
There was also a very lo-fi method of totting up the scores.
This is from Broadcasting House in 1951.
By 1959 the swingometer had made an appearance – but not quite in the same form you see it today.
Here is that first swingometer in all its glory.
This version, from 1964, is a bit more like it.
In 1966 the studio was still cramped and full of bulky cameras.
By the '70s, the broadcasts may have been in colour but things were still pretty low-tech.
And it was clear, even to the BBC, what the main attraction was. By 1979, the swingometer was starring in this photo call alongside Angela Rippon and a fresh-faced David Dimbleby, making his election night debut.
Come 1983, Peter Snow was experimenting with some *very* early electronic graphics.
Four years later, and Dimbleby was firmly in charge, with some very '80s-looking graphics behind him.
This was the golden age of the election graphic – and of Peter Snow. Here's how they looked in 1992.
By 1997, the BBC team and the swingometer screen had moved into even more spacious surroundings.
But it all started to go too far. In 2001, there were floating houses of parliament and all sorts of other digital gadgetry, including "news stairs".
And in 2005, someone had the equally bright idea of trebling the swingometer's size.
Then Jeremy Vine took over swingometer duties from Snow, bringing with him some whizzy green-screen graphics.
Still, amid all the whizzy graphics, it's good to know that some things remain the same.
Long may he reign as the unofficial king of election night... even though this year is his last.
