See what a little creativity "can do"?

Hi Asami,

In the first sentence, you emphasise on your liking for the advertisement. Perhaps it was unusual, perhaps it was funny or perhaps it was ironical. In your sentence, it was the creativity of the advertisement that has sparked your interest, attention and liking for the advertisement. 

This arousal of your interest, attention and liking is what the creativity "can do". (What the creativity of the advertisement "can do" is to arouse your interest, attention and liking for it.)

Grammatically speaking, when we say something or someone "can do it/something", we mean an ability of something or someone to achieve something. 

Usually, we say : "....... can do it/something."

However, the "it/something" is eliminated in your sentence as it can be implied from "I love this ad" that "it" refers to sparking your interest in a good way.

Example:

An inculcation of love for knowledge is what skillful educators can do.

Hope this helps.

Cheers, 

Lance

- 

in this sentence, the creativity is the thing that is doing. What is it doing? 

The sentence means that the creativity in the ad does a lot / makes a big difference.

the sentence means the same as " do you see how much good a little bit of creativity does?"
