        Due to a bug in how iOS handles webgl instancing, this animation
        performs incredibly poorly on iOS—to the point where it doesn't really
        work at all. On my phone, it runs at 0.0075 fps and makes my phone
        heat up to the temperature of the sun.

        I'd recommend trying this on desktop (it also just looks better), but
        if you really want to see what happens on iOS, you can
        <a
           href
           @click.prevent="
                           showIosWarning = false;
                           status = 'playing';
                           "
           >
          proceed anyway</a
          >.
      </p>
    </div>
    <div class="help" v-show="showHelp">
      <h2>Instructions</h2>

      <p>
        This experiment visualises images as collections of animated coloured
        particles.

        In addition to providing a few images (selectable on the configuration
        in the top right of the screen), it also allows you to upload your own
        by dragging and dropping them .........完整代码请登录后点击上方下载按钮下载查看
