Say a word twenty times in a row and it stops meaning anything. Rauno Freiberg
[points out](https://rauno.me/craft/novelty) that interfaces do the same thing:
the flourish that delighted you on day one is invisible by day ten and in the
way by day one hundred.

He borrows a rule from film, where around 10% of the frame is the accent
color, and suggests making 90% of an experience familiar and 10% novel. Think
of that 10% as a **novelty budget**. The question isn't whether to spend it,
but where.

Finish a few tasks and clear a list, in both modes.

When everything animates, nothing stands out and the whole app feels slower.
When only clearing the list animates, that moment lands.

## Spend by frequency

**The rarer the moment, the more expressive it can be.** Benji Taylor calls
this the [Delight-Impact Curve](https://benji.org/family-values): the potential
for delight goes up as the frequency of use goes down.

- Hovering, switching tabs, checking a box. These happen constantly. Spend nothing here.
- Opening a dialog, sending a message. Occasional. A short, quiet transition is plenty.
- Finishing onboarding, clearing your inbox, a yearly recap. Rare. This is where the budget goes.

Some moments should only happen once. On Rauno's Devouring Details, the
welcome transition plays right after you log in and never on a reload.

## Count the cost

Small delays compound. Drag the sliders.

A 300ms transition you see 200 times a day costs about six hours a year. That
is a lot of waiting to spend on something you stopped noticing in week one.

## Novelty taxes learning too

New interaction patterns cost more than new visuals, because people have to
learn them before they can use them. Rauno calls this the novelty tax, and
points to Arc: a browser its fans loved, that most people found too much to
learn.

None of this means "no delight". It means a calm baseline, so the one loud
moment has something to stand against.
