I'm not an individual.

A brief departure from the world of fine art.

This mural is found at Chichester Railway Station UK, just over the thoroughfare where crowds of passengers hurry by.

As far as I could tell, it was not associated with any advertising, nor with any information programme.

But we can consider it as a candidate for 'artwork' status.

So what's going on here?

This has been painted/stencilled/applied in a prominent position. In particular, it has been placed above a staircase where crowds of busy people will pass. As you begin to descend the stairs, the mural is at eye-level - large enough to be easily read, even by someone in a hurry. And it is quickly passed. It quickly becomes a memory, if that.

And what do we have, by way of composition? 18 identical boxes - identical, that is, except for two. One has been tilted on its axis. One contains the words "I am not". Apart from the one containing text, all of the boxes contain an identical tick: the sign of approval, agreement or affirmation.

To a British viewer, tickboxes bring a number of things to mind.

• The endless round of forms and surveys which makes up part of modern life.

• A contemporary business attitude where a task is complete as soon as a box is ticked (regardless of whether the job has truly been completed or not).

• A register of presence or attendance which records that you are here or of the same mind.

We are all here.

We've done what is required.

We can relax now, because one task is out of the way.

But one square is having a wobbly. It's been ticked, but then it seems to have lost its confidence or certainty. It looks like it might be about to literally drop out.

And the other one hasn't even got as far as ticking the box. Instead we have a bald statement "I am not".

Not what? And why aren't you?

No answer. This is all you're going to get from this box: a firm statement, clear as far as it goes. Whatever else is going on, this box is having nothing to do with whatever game the others are playing.

Which box is you, oh busy traveller, rushing to your office or appointment? You might not have thought about it before, but now the question has been put you can no longer avoid it.

So, Art Lovers, is this art? I think it is.

The artist has presented us with a concise and easily read symbol of the-way-we-do-things-now. S/he hasn't used words to explain it. There is no accompanying label with an article on the tension between individuality and 'herd instinct'. Nor does it (really) offer a view about which is the better box to be. All this we have to work out for ourselves, prompted solely by an image.

And for me, it is this power of the image which makes the strongest claim for this being art. To put into words all that was conveyed by the image, required several paragraphs. And one is still left with the feeling that there are many more possible meanings.
