Watch a digital circuit explain itself.
Narrated walk-throughs of digital logic — from a single AND gate to a working CPU. A virtual professor explains a real, interactive circuit in your language. Pause anytime and play with it yourself.
There's a lesson forwherever you are.

Hook: a CS undergrad's quote — "got me through digital logic finals" or similar. Should reference a specific lesson (D flip-flop, ALU) so it's concrete.
Hook: an instructor's quote — "I assign these as pre-lecture work" or "the embed plays right inside our LMS." Validates the teaching use case.
Hook: a self-learner's quote in a non-English language (zh / ja / es / de). Proves the multilingual claim with a real voice, not just our marketing.
