My first ever auction: An Exciting Time for Artists!

With all the excitement around NFT (crypto) art among artists and collectors, I started my gallery at Hicetnunc and was pleasantly surprised by the sales on the first day.

Since Hicetnunc is just starting, it does not support auctions or reselling at this time. (Update: reselling at the secondary market is now active.)

Today, I minted a new piece of generative video titled “An Exciting Time for Artists” at and put it for auction, simply because of my curiosity to see how it works.

Here it is:

Description of this piece:

An Exciting Time for Artists is a celebration of the bloom of NFT art in 2021. Having been working in the new media industry for almost 3 decades, swfoo (Dave Yang) is finally seeing the technology of decentralized assets and visual arts becoming mainstream.

Inspired by Dave’s background in computer mathematics and visual arts, the foundation of this video is represented by the colorful shifting mathematical Voronois, where organic visuals on top are constantly moving and changing directions in this exciting time for artists.

This one minute video was created in Lua and GLSL shader.

In case you are not aware of Hic et Nunc (latin, meaning: Here and Now), it is getting a lot of attention from artists for good reasons. It does not rely on eco-unfriendly currencies such as Bitcoin or Ethereum. It uses Tezos which is much more energy-efficient and the minting fee is minimal. The minting fee for other sites or blockchains can be a hurdle for some artists since it can be quite high. Why pay the much higher upfront cost to mint a digital item before there is guaranteed sale? There is no curation or wait list at Hic et Nunc, so artists can put up their work for sale with minimal cost. Since Hic et Nunc is just starting out, it may not be for everyone. No matter where the digital art is sold, this is an exciting time for artists!
