IRIS Machine Electroencephalograph Headset (with IRIS Machine functionality)
The IRIS machine system consists of two integrated components: 1) The Electroencephalograph (EEG) headset worn by Professor Clegg during the UNIT brainwave experiment, with thick padded ear cups enclosing sensitive sensors that transmit bioelectric signals from his brain via trailing wires to the main machine, and 2) The main IRIS diagnostic device embedded within UNIT's laboratory, featuring a cathode-ray oscilloscope-style monitor that displays neon-green spikes of raw psychic brainwave data in real time. The combined system translates neural impulses into jagged electrical patterns through control panel dials that whir into alignment, while also projecting dangerous interdimensional psychic phenomena (such as the Metebelis Three crystal's embedded curse manifesting as a monstrous spider symbol) when Professor Clegg's brainwaves register. Both the headset and machine appear clinical and utilitarian against institutional-white laboratory walls, their metallic frames cold as they expose the truth of Clegg's telepathy and the scope of the Metebelis Three threat.

Purpose
To monitor and record brainwave activity during controlled psychological experiments, enabling precise measurement of psychic phenomena
Significance
The headset becomes the conduit through which two truths emerge: Clegg's suppressed telepathic abilities and the Brigadier's violated privacy. Its readings validate the Doctor's hypothesis while forcing Clegg to confront the corruption of the Metebelis crystal.
