My Psionic Sigil Board. I should also mention that the aluminum foil is for conducting psychic energy and is also a geometric pattern amplifier. Also can be used for broadcasting several sigils at once. With the light from the candle as a carrier for psychic energy. Although I would have liked to use copper foil instead of aluminum, I used what I had at the time. It is simple but effective and like all psionic machines and radionics for the matter the intent and will begins with the practitioner.
