Infectious is an online shop with artistic adhesive skins for laptops, phones and cars. It is based in San Francisco. They regularly organize online design challenges open for everyone based on a community voting. Winners get 1000$ in cash + 100$ on Infectious products + their design printed and put in Infectious shop.I love Infectious and their art! They are very demanding. The designs which they put in their voting gallery are carefully selected. Only the best designers win and can be very proud. You can buy their products and make your laptop/phone/car look very original and attractive.
