The logo grows a letter every time you turn the page
Page one says google. Page two says gooogle. By page thirty you’ve got a word that no longer fits on the screen and a scrollbar underneath it, which is the point where most people start scrolling sideways just to see the end.
The colours cycle as the o’s multiply, so a long word turns into a stripe of blue, red, yellow, green repeating out to the horizon. It’s the same six-colour sequence, just stretched past the point of sense.
Where it came from
This wasn’t planned as a joke. Old results pages numbered themselves inside the logo, one o per page, and somebody noticed that going deep enough made the brand name absurd. The bug became the bit.
What to do with it
Press the jump button and watch ten o’s arrive at once, each popping in with a slight bounce. Press the absurd one and the word gets long enough that the counter is easier to read than the logo. There’s no cap that matters; the browser gives up before the counter does.
The width readout
Under the meter there’s a running character count. It’s a small thing but it’s the fastest way to explain to someone why the page is scrolling sideways.
Other old-web oddities
If stretched logos are your thing, the wider archive of retro tricks is worth a wander. google in 1998 brings back the original homepage, complete with the beta exclamation mark and a stack of links that look nothing like a modern search page.
For text that plays tricks in a different direction, google mirror reverses every character and still lets you search. google terminal throws out the interface completely and gives you a command prompt instead.
Then there’s the visual stuff. google matrix turns the page into falling glyphs, and google fan blows the letters clean off it. Same logo, very different fates.
