I've been a little nonplussed by some of the exhibitions FACT have presented over the last few years. I've never had any qualms about the curation or usually the choices and quality of artists and work, but I have wondered about the accessibility of some of the works to what you might call the general public.

One or two of the exhibitions I've seen at FACT have hardly been what you'd call family friendly or - for that matter - any good, which raises certain questions about the use of public money to exhibit something accessible only to a tiny proportion of aformentioned Joe. This show from sister gallery Experimenta goes a long way to redressing the balance, to such an extent that I can well imagine crustier types raising an eyebrow in dismay.

Experimenta's installations all invite an element of interaction to varying degrees: requiring an effort of physicality, movement and consideration on the part of the viewer. Best of the bunch is Dislocation, with its selection of CCTV cameras intermeshing live feed with prerecorded viewers milling around, apparently behind you, the viewer. Some seem oblivious to you while others will try to interact with you.

The difference between reality and make-believe becomes bizzarrely, and uncomfortably, confused as soon as other visitors enter the room. It is quite affecting. Expecting turns the notion of interaction on its head with a disquieting and unexpected reaction to the viewer's innocent actions. It too is hard to forget.

At the other end of the spectrum is ZiZi The Affectionate Couch - rumbling, farting and squeaking contentedly whenever someone parks their backside upon it - and The Shy Picture with its nervous inhabitants. The latter is particularly satisfying as a work in itself, casting the viewer as voyeur and inviting rumination on the relationship of subject and object, but also as something that is light and witty, accessible to kids and kids-at-heart alike.

Some of the exhibits arguably go too far towards rewarding the viewer's sense of fun, but not stimulating much beyond. Virsual - The Digital Rocking Horse and Op Shop wouldn't seem out of place in a fairground. The visually interesting Pataphysical Man is trying to pass itself off as something it's not, to wit: "the science of imaginary solutions, which symbolically attributes the properties of objects, described by their virtuality, to their lineaments: in Gestes et opinions du Docteur Faustroll, II, viii" Thanks for that.

It seems unlikely to me that this exhibition has coincided unintentionally with school holidays. I have no problem with that at all. Experimenta Under the Radar is a superb collection of oddities, uncanny and out-and-out fun in pretty much the right quantities for attracting people outside of the usual gallery-going set, and I hope FACT will be rewarded accordingly with a new generation of viewers.
