Sprint 1
Research, scoping, and initial prototyping
During the first sprint, we focused on researching and scoping the project. We found early on that there have not been a lot of interactive laser, phosphorescent material systems, so we decided to prioritize user control of the product.
Touchscreen Research
We initially wanted to make the sphere itself into a touchscreen, but this was prohibitively expensive. We also considered a cylindrical shape, but this change didn’t do much to fix the cost issue. Flashier options exhausted, we decided to use an external, flat touchscreen. However, the priority for the minimum viable product was to have the simplest possible working system, which did not require touchscreen input.
Other Research and Initial Prototyping
We also researched the other basic required components of our system, such as phosphorescent
material, servos, and laser diodes. These elements were significantly less problematic, and
did not seem to require immediate rescoping. 
We ordered a number of parts and got started on a first-pass design.
Towards the end of the first sprint we began working with the touchscreen, despite the fact that it was not included in our MVP. We didn’t have the right adapter for the touchscreen for interfacing with the Arduino, so this early work wasn’t successful.
