ChromaStone is a retro interactive arcade game, designed by applying genetic algorithms. The game starts by randomly choosing a random default colour. Now, the player needs to tap the panel with the default colour to score a point. The better the motor and visual reflexes, the greater will be the score. It can be played as 1 vs 1 and 2 vs 2, measuring the points within a minute between the opponents.
We took the arcade style game machines as our principal inspiration. The intense colours and rapid physical interaction are the main elements of an arcade-style game of the 90s. Simple design, ascending difficulty, the score is the final goal, a time limit and minimal interruptions, are the characteristics to use it for inspiration.
To design Chromastone, we tried something new. First, a universe with certain spatial dimension is created. Then, there are random nodes created in the 3d space. And finally, there can be connections between these nodes.
A set of random Chromastones were generated. The simulation is done using Rhinoceros 3D and Grasshopper. The plugin is called Biomorpher, and it helps convert Genotypes into Phenotypes. The selction procedure is done manually by human eye. The aesthetically pleasing organisms get to live and have offsprings and the ugly ones die off with generations. After 10 iterations, a final design is selected.
A modular system of panels are used to house all the sensors and LEDs. The electronics are sandwiched between top layer of polypropylene sheet and a bottom layer of MDF to give it a structure.
The articulating segments used in the constructions are 8mm iron rods. They are cut and welded according to the CAD model generated by the genetic algorithm. We welded the planer rods with the help of marking the angles on a sheet of MDF. After welding the parts, the edges were pulled and smoothed (especially the nodes). The structure was later sent to be painted electrostatically by applying coats of RAL 1016.
The harsh reality about translating CAD information into physical world is the fact that artifacts are inevitable. There were minor differences at the bottom of the structure. But as the differences keep getting larger up top, as the human error starts piling up.
