What new words do we need to describe things?

[rhubarbcrumbles]

I need a word for that feeling of pleasure when somebody recommends a book for my kindle and I discover I've already got it but had forgotten.

What words do you need that don't exist?

The thing on a screen that whirls round whilst waiting for something to load on a computer
It's not a cursor I don't think
A bit like the whirly thing at top of page when waiting for MN threads to load

The little brrrrrring noise that cats make when they are asking you questions

A bit like the whirly thing at top of page when waiting for MN threads to load

Wikipedia says it's a Throbber. Hmm!

I thought the whirly thing was called a daisy wheel...

Someone needs to give whatever it is a decent name! Throbber??Daisy wheel is too much of a mouthful
