This quintessential Deep Cheque, started in 1990s and now extended with new technologies, is about Depth. As a Versioned Edition, remember, it is re-created on each issue - you can add your own elements !

our lives are so often flat, dedicated to keeping afloat or crawling along. yet - there are many ways to explore the Depth dimension - probing, falling, sliding, sinking... my preferred one is Diving, which implies possibility of a speedy return.
but - upon reaching the bottom i hear knocking from underneath (says one Polish writer) - all is relative...
have a nice day, Visitor!
