Isn't this the crux of the NSO Group exploit on Iphones?

FWIW, I can't figure what to do on the "ride the line" level. I don't understand what the motors do exactly (powering both motors simultaneously makes the car go sideways) and what the sensors are sensing.

#26Brilliant idea! That logo however is the most repulsive piece of artwork I've seen in a long time. (I am sorry for being blunt)

#27As a complete layman I wonder if there’s a future where you could use a picture/X-ray of an old CPU architecture and simulate it blindly with an approach similar to yours?
In the summer of 2009, working from a single 6502, we exposed the silicon die, photographed its surface at high resolution and also photographed its substrate. Using these two highly detailed aligned photographs, we created vector polygon models of each of the chip's physical components - about 20,000 of them in total for the 6502. These components form circuits in a few simple ways according to how they contact each other, so by intersecting our polygons, we were able to create a complete digital model and transistor-level simulation of the chip.
This model is very accurate and can run classic 6502 programs, including Atari games. By rendering our polygons with colors corresponding to their 'high' or 'low' logic state, we can show, visually, exactly how the chip operates: how it reads data and instructions from memory, how its registers and internal busses operate, and how toggling a single input pin (the 'clock') on and off drives the entire chip to step through a program and get things done.

The project is super cool but I agree the logo is a terrible example of it in use. I'd love to see a more easy to digest example. The logo circuit is confusing and I'm not sure what to make of it.
It shows the four basic logic gates, a one-bit adder, and simple digital clocks. I'll add these to the git repo in a bit!
