The #HEN500k event was created in celebration of the 500,000th OBJKT being minted on Hic Et Nunc. During this event artists are encouraged to participate by minting art with editions of 500 at 0.5 $tez or less a piece. This event is not run by Hic Et Nunc but was encouraged by the official Twitter. Events like these are a great way to discover new artists and allows a chance to collect trending artists artwork for cheap.
Here are some other pieces created during the #HEN500k event.
