There are a number of tech demos that I've did during the 2020, some were learning projects, some were done as excercise. It's split in two Unity projects, one is built with HDRP and other one is on legacy targeting mobile devices.

• One deals with mesh generation, it asks a user to draw a shape and then generate a mesh based on that shape, which is then put into a physics playground where you have to navigate it through the obstacle course.

• One deals with mesh deformation, user swings a lightsaber, which dynamically cuts the mesh on the screen in two.

• One is a mobile project, in which user drives a truck clearing the snow off the road, with few other cars following him:

• One is, arguably, the most over-engineered tetris to ever exist - DI, MVC, injection, whole nine yards. Plus a nice ice cube shader:
