Rather than make new devices that will turn into e-waste after the event, we're recycling old price tags into networked conference badges. https://github.com/osresearch/eink-pricetags
New images are sent to the tags using the A7106 radio module from another tag, driven by gpio from a Pi. https://github.com/cibomahto/pya7106

So you could generate art with a chain of those tags that travels from one tag to another and mutates over time.
Great work!
@momo tag-to-tag communication is possible, although battery life is a challenge - RX mode takes 18mA, compared to sleeping 5uA. https://github.com/osresearch/eink-pricetags/issues/8
@th I was missing the k when typing.
