PLATE III
An oracle for one. Tune a brass dial; a rendering of you, thirty years on, appears on the screen and answers. The trick — proven by the analog predecessor — is that the future self knows nothing you don't. The device just asks the questions that release the answer.
Vintage brass-trimmed cockpit television. Stripped Soviet tank radio for the dial. Two-way mirror over an LCD; a hidden camera reads the face. A Raspberry Pi underneath keeps the ritual running. The oracle does not predict — it gives you back to yourself, late.
