If you have always wanted to dangle a bunch of stupid crap off your cellphone like the Japanese, but lacked a built-in ring for this purpose, you are in luck. Strapya has a solution.
The answer is simple: adhesive buttons. Just place them on your phone and insert the strap of your choice. The only problem is that once the buttons are attached, they are going to be a real bitch to pry off. So you might be SOL if you change your mind and decide that you don't want your phone looking like a candy-coated nightmare. [Strapya via Inventor Spot]
