I've recently launched the minimalistic drawing app okso.app that allows you to do interactive (nested) sketches. And, as a continuation of my previous S.O.L.I.D. Principles Around You article, I've organised it in interactive sketches that you may find here.
Check what I've got:
So, each SOLID principle has a dedicated sketch page that look like the following
Single Responsibility Principle
A class should have only a single responsibility. Only one potential change in the software’s specification should be able to affect the specification of the class.
Open/Closed Principle
Software entities should be open for EXTENSION, but closed for MODIFICATION. Allow behavior to be extended without modifying the source code.
Liskov Substitution Principle
Objects in a program should be replaceable with instances of their subtypes without altering the correctness of that program.
Interface Segregation Principle
Many client-specific interfaces are better than one general-purpose interface. No client should be forced to depend on methods it does not use.
Dependency Inversion Principle
One should depend upon abstractions, not concretions.
- High-level modules should not depend on low-level modules. Both should depend on abstractions.
- Abstractions should not depend on details. Details should depend on abstractions.
In the future I plan to add more visual explainers like this one to the okso.app showcase. Currently there is a Data Structures sketch is available that is done in a similar style as SOLID one. I hope having such visual explainers in one place will be convenient for you.

Just one thing to mention: This is a genius article.
Nice way to explain SOLID principles
The tool looks great! I especially like the page concept to organise scetches in nested structures.
I might try it as a replacement for excalidraw.
This is great.
I've always had trouble explaining to new devs what the Liskov Substitution Principle means. This is the perfect example.
Amazing article!
Awesome!
What a surprise!
I have intended to write articles about the SOLID principles and indeed have already written about the SRP and OCP.

Wow very nice both the app and solid presentations
