Got info about this contest in my inbox and I thought it may be of interest to some members here on BSFS. The goal is to create a 3D artwork to celebrate the 50th anniversary of NASA's Apollo program. The one catch is that you have to use Adobe Dimension to render the final artwork. A one month subscription to Dimension is $21, so I guess that can be considered to be the entry fee. The registration deadline is Jan 14, 2019.
