The larger it is the more cost in materials, transportation, insurance, and fabrication labor, involving many people.
The BMORG art foundation provides a fraction of the budget and I believe they retain a commodification percentage post-playa.
A startup in Las Vegas, Transfix - https://news.artnet.com/art-world/trans ... as-2262410, set up "the worlds largest interactive art park" on the grounds of Resort World. It included artists Duane Flatmo, Christopher Bauder & KiNK, Marco Cochrane, Foldhaus Collective, Christopher Schardt, Playmodes and HOTTEA, many burner artists.
After the event, Transfix was supposed to return the art to the artists. Now the artists are scrambling to rent heavy equipment to move their art off the property as demanded by Resort World. Resort world brings in their giant Christmas tree display to replace it.
(The interactive Van Gogh company, Lighthouse Immersive, is also going bankrupt)
Big art is big money and a big risk. There is a famous saying in art, "if you can't make it good, make it big, if you can't make it big, make it red, if you can't make it red, export it to another country and import it."
Some of the most moving art on the playa is small and intimate.
You can look up all the Transfix details in a news search and FB search.
