Had this dream where I was organizing all my EDC stuff using modular cube-shaped containers that could snap together in different configurations. Woke up and actually sketched it out - turns out there's nothing like it on the market for gear organization. Been working on a prototype ever since and it's actually pretty functional for keeping all my tools sorted without taking up tons of space The weird part is in the dream I was solving a Rubik's cube while explaining immigration law to someone, which is just peak me apparently

In 1975 it was a crazy dream of opening up a US Bicentennial 1776-1976 merchandise store.
