Scholarship on the finance-security nexus has typically been concerned with ‘first order’ phenomena, such as the interpenetration of the finance and security sectors. This article contributes to the debate by turning to an apparent epiphenomenon, namely The LEGO Movie, and using it to address some overlooked intersections between popular culture and the finance-security complex. The analysis first focuses on how finance and security are represented in the film, through the plot and the fictional company at the centre of the film's conflict, to its LEGO minifigure characters and the playsets featured therein. The focus then shifts to how the LEGO Group's business model informs the film in significant ways, from the plot's motivation and structure, and the mise-en-scène, to how the film was produced. My argument throughout is that a seemingly innocent or insignificant film in fact participates in the financialization and securitization of daily life through its very style and status as a cultural product. Key here is how The LEGO Movie does this in ways that confound possible critique through the use of irony and cute aesthetics, as well as through its own supposed triviality.

Physical prototyping is critical activity in the produce development process, but the cost and time required to produce prototypes hinders it use in the design process. Hybrid prototyping through coupling LEGO and FDM printing is presented as an approach to address these issues. After establishing the separate design rules for FDM printing and LEGO, this paper created new set of rules called Design for Fabrication (DfF) for hybrid prototyping. These cover the three main considerations (Technical, Process, and Design) that the designer and process planning must include to practically implement LEGO and FDM hybrid prototyping. The DfF rules were considered in a prototype of a computer mouse. While the fabrication time was not reduced as expected, it showed that the rules could be practically implemented in a real-world example. Additional considerations were identified that are to be included in the DfF rules.

Further work is required to realise the predicted step-change reduction in fabrication time. The first approach is to leverage multiple printers to parallelise the printing. The second is to reduce fidelity while maintaining high fidelity in key regions of interest.

This paper presents an approach to the automatic generation of electromechanical engineering designs. We apply messy genetic algorithm (GA) optimization techniques to the evolution of assemblies composed of LegoTM structures. Each design is represented as a labeled assembly graph and is evaluated based on a set of behavior and structural equations. The initial populations are generated at random, and design candidates for subsequent generations are produced by user-specified selection techniques. Crossovers are applied by using cut and splice operators at the random points of the chromosomes; random mutations are applied to modify the graph with a certain low probability. This cycle continues until a suitable design is found. The research contributions in this work include the development of a new GA encoding scheme for mechanical assemblies (Legos), as well as the creation of selection criteria for this domain. Our eventual goal is to introduce a simulation of electromechanical devices into our evaluation functions. We believe that this research creates a foundation for future work and it will apply GA techniques to the evolution of more complex and realistic electromechanical structures.
