Hey @Paling - this is a good feature request. I just want to be sure you know about [PixelTeleporter](https://forum.electromage.com/t/pixelteleporter-virtual-leds-on-your-computer/531) from zranger1.

You use a cheap Wemos ESP board to receive pixel data out from a Pixelblaze, and receive that data over USB into a computer. From there, it’s displayed by Processing and played through your Pixelblaze map on your screen. It took me about an hour to get set up, but it’s been essential for previewing and developing patterns when I can’t easily see the final installation (it’s not built yet, or I’m freezing cold in a lawn chair).
