With some off-the-shelf glow-in-the-dark inkjet transfer papers for dark fabric I was able to make my surreal coffee art and self-portrait fractals glow. You can do it too and here is what you need from Amazon for the technical part! Besides that you might need a UV light to recharge the phosphorous but any strong light will do the job.
Here is a fractal self-portrait glowing in the most tenebrous of darks!
Here is a replica of my absurdist coffee painting "We inhabit a pussy tailed universe" glowing on my T.
Remember to save energy to save the planet. Make glow-in-the-dark T shirts not war :)
I promise to post more often in case anyone is reading and the web statistics do not lie. Drop me a note or just "hi". Happy 2014 and 2015 just in case :)
