SandScene

Art created by the game in Sakura mode

Inspiration

Divine intervention. No joke. It just came to my head instantly. Seriously. This is not how my brain works work. I usually spend 18 hours at 24 hour hackathons just trying to find one idea.

What it does

Pours color-changing beautiful sand using physical tilt controls via an MPU and CV to track the left and right movement.

How I built it

I used C++ with SDL3 for the main app, as well as OpenCV and AprilTag to track the left and right movement using my phones camera, and an MPU6050 with a Raspberry Pi Pico 2 W sending the data.

Challenges I ran into

My main challenge was the 4 day time limit because I joined the hackathon very late and wasting 2 of the days trying to make the cup actually contain sand and failing because of hitboxes, only to realise the cup didn't need to actually contain sand and could just dynamically spawn it instead.
