Hey Tek-ninjas! I hope you all will indulge me in a moment of self promotion.
Over a year ago I made myself a pair of custom shoes to wear for trade-shows and conferences that celebrated PECS and AAC. I received a lot of positive feedback, and people inquired where they could buy them.
I now have those shoes and a few T-shirts available for your acquisition here, or above in the menu Tek-merch.
