Submission Guidelines

Theme — Hacking the Tower

  • Hacking, encryption, decentralization, smart contracts, open source code, interoperability, and blockchain technology.
  • Content can be any video or moving image that is appropriate for ALL AUDIENCES.
  • You may incorporate the windows as wall surface, nevertheless we encourage submissions to integrate with the structural qualities of the building. Remember, this is a video-mapping projection. Take advantage of it!

Length of Content

  • We will accept pieces of art from 30-seconds up to 5-minutes in length. Please propose video lengths that make sense for your artwork. We may request edits to length.


  • Ideally work at a slower speed works better (fast movement doesn’t work well at this scale).
  • Recommend clips under 5 minutes in total, with 2.5 mins being a sweet spot.


Mapping Mask:

IMPORTANT — Please send the files in exactly the same layout as the mask. The video system will automatically rotate the content 90-degrees.

Projection Specs:

We are using ten (10) 21,000 lumen laser projectors made by Digital Projection, Inc, with five (5) each covering the top and bottom of the Tower. The playback software & media server is Analog Way’s Picturall Pro.

What is Night Lights Denver, the program willing to host this content? Night Lights Denver (NLD) is a permanent projection mapping installation from the Denver Theatre District (DTD) to support innovative artists with an experimental platform, featuring content that rotates on a monthly basis, designed by artists and our local community.

NLD currently projects artistic, civic, and creative content on the Arapahoe Street-facing side of the historic Daniels and Fisher Tower, also known as the D&F Tower. All of NLD’s programming is free and open to the public, and they are not allowed to do ANY advertising on the Tower. As they hope to expand with more locations, this installation is subtitled “The People’s Projector.”
