Dash has been working on these wristbands for a long, long time. Canonically speaking, he was working on them as far back as the second issue of volume one.
Dash also was working on these wristbands during Pause & Effect and Signing Bonus. He hit a breakthrough when offered nanotech data by Kimney in Under New Management.
We see the bands again, in FTL.
Pretty neat, huh?
[…] Dash invented something new in the latest Cosmic Dash. […]
That’s exactly the kind of thing we all dream of inventing once ‘inventing’ starts meaning something cool.
