The Login Log is a collaborative speculation design project that operates on two levels. Firstly, and drawing on concepts from actor-network theory, ludic design, and idiotic objects, it is an exploration of how a “nonsense object” can help to build connections between makerspaces and other creative communities. To this end, a research-creation plan was devised to introduce a “joke object” to a series of makerspaces for the successive addition of new useless features. Secondly, it is an exploration of “mess”; how research-creation may proceed when initial expectations are disappointed, and how we can use this mess to create new opportunities for inventive problem-making.
