Dreamachines (3) with EEG in The October Gallery :
On the 19th of September 2015 I presented a keynote about A history of Flicker from Purkinje, Helmholtz, Grey Walter, and Brion Gysin followed by 1.5 hours with multiple special LED DreamMachines in a session for 30 paying guests upstairs in the reading room.

Dreamachines : in Deal (with Beats photographer Harold Chapman, August 2015)
We travelled to meet Harold and friends in the MOMI, Deal for an afternoon session with unexpected beneficial after-effects.
‘Lates’, The Science museum, March 2015, South Kensington, London (free)
From 6.30-9.30pm we were exploring the phenomenon of Theta brainwaves entrained in guests who patiently waited in the queue, through the phenomena of ‘Flicker’ from an eyes-closed Dreamachine experience.
‘Build your own Dreamachine’, February 2014, FACT, Liverpool
I have given workshops and presentations about The Dreamachine, the effects of “Flicker” and how Human EEG entrains in response to these photically induced frequencies in Theta and Alpha brainwaves.
This led me to produce the artwork “Analogue Oneironism” which involves monitoring the participant’s brainwaves whilst they experience with their eyes shut, the effects of ‘Flicker”. The brainwave’s are converted into interactive variables that modulate a multi layered sound composition, allowing dynamic versions to be generated by an audience, from one score.
The design of a dream machine template is graphically so to elicit an alpha wave state via the flickering photic stimulation.
It can be observed during this experiment the subject repeatedly and often settles into an Alpha/Theta wave state across both hemispheres through exposure upto 15 minutes duration. Entrainment visible after 2 minutes, with no Beta, and 8Hz maximum frequency.
