I ran across this project in the r/linux community a few months ago. Thought it may interest some here.

Got me thinking if it would be possible to set up something similar with keyboards. Have a base 60% board. Then snap, via magnets, on a num row. Snap on an arrow module. Snap on a function row. Snap on a full ten key, allowing it to be on the left or right side. An embedded, auto flasher to re-flash firmware to some preset configs to help transition between module setups. For example, remap that pesky escape/grave key placement.
Not really sure why one would want such a setup at the moment, but the community is not always purely efficient minded. Sometimes things just need to be made…
