Our second #ossart entry is dedicated to Stack PHP, a PHP middleware reference implementation by Igor Wiedler, Beau Simensen, and Christoph Hochstrasser.

We sent a few teaser images out on Twitter (you're following #ossart, right?) and we got a few guesses! The first person to correctly guess the project this time around was @mwop! Nicely done!

Now that PSR-7 under review, Stack PHP may soon be undergoing a transformation into something... different. Follow @stackphp to learn more!

The original piece measures 10" x 20" and will be available for purchase in February!

We also have prints available for purchase now starting at just $20!
