                                                            Artists and architects who want to experiment with interactive spaces and
                                                            responsive systems, particularly on large, urban-scale projects, are often
                                                            prevented from doing so because of the complexity, logistics or costs
                                                            involved with such systems. Prototype research seems prohibitively
                                                            expensive and the most interesting concepts and approaches remain on

                                                            Alternative channels for financing and development need to be found;
                                                            one way to pursue this line of work is to develop a suite of low-tech
                                                            sensors and interactive actuators that can be produced inexpensively
                                                            from off-the-shelf toys and devices. These ‘hacked’ devices can form part
                                                            of a ‘kit-of-parts’ that new media artists and interactive architects could

                                                            Operating with low tech interfaces, sensors and actuators as we
                                                            advocate here is one step closer to opening up the tools for appropriation
                                                            and recombination to a wider audience and a wider production base. The
                                                            advantage of working with low tech toys and devices is that very little
                                                            specialist knowledge is required. It is perfect for a design process where
                                                            imagination is in abundance but budgets are not!
                                                            Here we present some examples of devices you can make yourself. You
                                                            may not be able to find exactly the same toy but chances are you will be
                                                            able to find something similar. Enjoy!
