Novelty Budget
Say a word twenty times in a row and it turns into noise. Interfaces do the same thing. The confetti that made you smile the first time is invisible by the tenth and annoying by the hundredth.
Rauno Freiberg's answer is to treat novelty like money. You have a small novelty budget, somewhere around ten percent of the experience, and the question is not whether to spend it but where.
Try the little task app below in both modes. Finish a few tasks and clear a list.
When everything animates, nothing stands out and the whole thing feels a bit slow. When only one moment animates, that moment lands.
Spend by frequency
The rule is simple: the rarer the moment, the more expressive it can be.
- Hovering, switching tabs, checking a box. These happen constantly. Spend nothing here, or close to it.
- 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 ever happen once. A first-visit intro that plays again on every reload is a bill the user keeps paying.
Count the cost
Small delays add up in a way that is easy to underestimate. Drag the sliders and watch the number.
Jakub Krehel did this math for a real product and it changed how the team thought about a 300ms animation. Delight needs a denominator.
Novelty also taxes learning
Every unfamiliar pattern asks people to learn your interface instead of using what they already know. A custom scroll, a gesture nobody expects, a menu that opens sideways. These spend the budget too, and they keep spending it every time someone new shows up.
Spend novel interactions even more carefully than novel visuals.
Contrast is the point
None of this means "no delight". It means a calm baseline, so the one expressive moment has something to stand against. The quiet parts of an interface are what make the loud part work.
