<h2>qrplay by nycki and SArpnt</h2>
<p>a QR-code sized implementation of ZZT Play, which you may know from the <a href="https://chriskallen.com/zzt/hallofmusic.html">ZZT Hall of Music</a>.</p>
<p>I designed this because I wanted a program I could print on a business card, and SArpnt found some clever ways to shrink it even further. The version on this page is commented, the version in the QR code is minified.</p>
<p>paste ZZT music code in this box, then click the button to #play!</p>
