@@qnaman not really. as the commenter said, the image of the train isn't even a functional circuit, it's just an image. if you did design a circuit that's also an image, it just requires a bit of creativity, you don't need "higher spatial abilities" whatever that's supposed to mean. more importantly what does that have to do with autism? having autism isn't a prerequisite of being creative or having good spatial ability. sportsmen and sportswomen need good spatial ability, as do plumbers, but presumably you don't need autism to be a good footballer or plumber.

@@amelted While CCD's were commonly used in optical sensors, they could also be used for other circuits. As the video explains, this is a shift register. It stores charge and shifts it from one element to the next. And eventually to an output or ADC.
@@amelted CCD just means a bunch of capacitors linked in some way. This chip is used as a small time delay by passing an analog voltage into each capacitor, and then on the next clock cycle into the the next capacitor: like a bucket brigade. Silicon is not cheap, and wasting 90% of the substrate on a picture would be insane, like $100 per chip at least.
@@videojuegos9379Since you've mentioned the bucket brigade: such circuits are/were used in the area of audio equipment for deliberately delaying audio: In order to make an audio effect called delay aka echo, dedicated delay devices used chips actually called BBDs, short for "Bucket Brigade Device". The amount of BBD stages aka capacitors as well as their clock frequency determined the delay time. Since the number of stages was predetermined by the chip model being used, the delay time could be adjusted by varying the clock. To make a real echo effect (ie with several repeats getting increasingly duller and quieter), the output was fed back into the input, with some variable attenuation to control the feedback amount aka the number of audible repeats. They were later replaced by digital delay effects, but at some point musicians and music producers realised that those analog BBDs had their own distinct 'character', as they were affecting / influencing the incoming audio in a way digital effects couldn't really do. Actually that's some kind of sound quality degradation, as besides of adding the echo effect, the sound wouldn't leave the BBD unchanged otherwise. However, that 'degradation' is usually perceived as something positive and desirable. For the largest part, it is just the higher frequencies being filtered away with an increasing number of repeats, which actually represents how echo works in nature. Also, changing the clock frequency while sound is being send through will change the pitch of the output. Digital echo effect units are just too clean and perfect for many people. The downsides are that BBD-based devices tend to be noisy and some kind of analog aliasing can be introduced depending on the clock frequency (if too far away from the optimal value). Besides of the typical echo use case, BBDs are also used for other delay/time based effects like 'chorus', 'flanger' or 'phaser'. All of them are based on delaying the incoming audio by tiny amounts in the millisecond range and then mixing the result aka the 'wet' signal with the original input aka the 'dry' signal in order to create phase cancellations. Feedback, additional filtering can also be applied as well as modulating the BBD clock with a periodic control voltage to achieve a wide range of effects. Ever seen those small boxes that guitarists are sending their e-guitars signal though and controlling those boxes via foot pedals / switches? If they are not fully digital, then it's likely that many of these effect devices have BBDs inside. Sorry for the length, I just couldn't resist nerding out on audio tech topics.

@@aleisterlavey9716 You can see these chips used often in guitar delay pedals, they're often called BBDs. Basically, its a shift register that has analog memory elements, so it can transfer an analog voltage down the line instead of just 1 bit at a time. You use it in the exact same way though, with one data input and a clock signal, and an output - some have an output in the middle. This is usually faster and cheaper than converting to digital and back, and you only lose a bit of precision, unless holding for a long time; the capacitors will equalize and you will get too small of an output.

Plessey had a similar train on tracks on some of their devices. But one day a new revision was being spun and the powers that be decided the extra time involved in putting the doodle in wasn't worth it and it was sadly eliminated from then onwards.

Once, on a specialty adapter board meant to be hidden in the guts of an IoT installation, I made a drawing of a man living in a house with a windmill attached, with corn growing in the yard. There are mountains in the distance, and a crescent moon with stars in the sky. I wrote this next to it: "This is Hobbleman's house. He hopes that, one day, the propeller on his house will make it fly away from here. But that day will never come. And Hobbleman will die alone. He will die terrified of death. And he will know he never really lived. He also likes corn." I no longer work for that company, but I still have the PCBs with Hobbleman's house on them.
