AS DAVID Shrigley has said a few times before the opening of his installation Life Model II, he's made a career out of not demonstrating many traditional craft skills.

That in mind, I felt infinitely better about myself after my shoddy attempt at drawing his giant sculpture that currently stands in the middle of Fabrica's floor. My effort at life drawing could be considered unorthodox, if not out-and-out bad. I liked to think it had a certain amateurish charm.

Reassuringly, the point of Life Model II is not to replicate the nude female model with unerring accuracy – although well done if you did – but to present your own take on the sculpture, expressing yourself in your own unique style.

Life Model II is a wonderful idea, based around public participation and creativity. There is no pressure involved – guests can sit or stand at their leisure and take their time over their depiction.

Once completed, visitors' drawings are pinned to the wall of Fabrica. As Shrigley has said, it's "art that begets other art". The artist's first incarnation of the installation, Life Model, was nominated for the Turner Prize.

If anyone is in any doubt that Brighton is a city full of talented artists, you simply need to take a glimpse at the fantastic designs currently adorning the venue, whose high ceiling adds a sense of ceremony and occasion to the event.

When I visited, some participants had opted for a naturalistic approach, portraying the model's angular cheekbones, flat fringe and outstretched arms in painstaking detail, while others had let their imaginations run wild and placed the sculpture in alternate realities or in a blaze of colour.

The greatest pleasure of Life Model II is seeing how different guests have interpreted a model that in itself almost defies interpretation. Other than the fact it towers above those behind the easels, there is nothing particularly remarkable about Shrigley's design.

It may have been self-delusion, but after the initial shame at my bizarre depiction I was able to convince myself that it contained some grain of artistic merit. Life Model II reiterates the point that there is no right or wrong way to make art, no manual to be followed.

If you feel like you need a creative outlet in the middle of a busy day, Fabrica is a shining beacon until the end of May.
