"Magic Sunmoon" is a UV (ultraviolet) blacklight fluorescent and glow-in-the-dark phosphorescent t-shirt / hoodie print, made from the original psychedelic spiritual visionary fantasy fine art backdrop painting by Symeon Nostrakis, and depicting a Magic Alchemy:
The Sun and the Moon come together in an Eclipse forming a Sunmoon,
the Symbol of the Harmonic Union of Male and Female, the Esoteric Union of the Opposites, and the Prime Universal Forces of Yin and Yang, the Two Complementary Halves that combine to create the Whole, with their common Third Eye inside a Lotus Flower growing from a Heart.
Above is a radiating Om / Aum, in the middle are the Two complementary Halves, and below is the Earth Globe, thus the One gives birth to the Two, and the Two give birth to the Many, while everything is surrounded by the Primordial Chaos of Stars and Colourful Clouds.
If you don't have a UV black-light, the t-shirt/hoodie will still glow in the dark and of course be visible in normal light.
For better glow-in-the-dark results place t-shirt/hoodie near a bright light source and allow at least 30 minutes for charging.
The brighter the light and the more time the t-shirt/hoodie is exposed to it, the more energy it will absorb and the more it will glow.
Additionally, the darker the room when you switch off the lights, the more pronounced the night glow effect will appear.
A black light source will charge the t-shirt/hoodie better and will make it glow more than a normal light source would.
Alternatively, you can use fluorescent lighting for charging (FT tubes or small CFL ecomomy lamps).
Old incandescent lamps cannot provide sufficient charging as they do not emit UV light.
