Here it is, and I agree, it is artless and ugly. A lot of Christian art is beautiful and uplifting, but fundamentalist Christians despise art, so when they create something like this, they ironically end up creating something that visually evokes the very modernism that they also hate. The Groom cross is 190 ft. tall, and can be seen from 20 miles away on I-40, thanks to the flat landscape in that part of Texas.
There's an identical cross in Effingham, Illinois. The Illinois people asked the Texas people for the plans, which they gave freely to their fellow Christians, then the Effingham group built their cross 8 feet taller! There is now a group in Richmond, Indiana trying to build a cross using the same design.
