We had a look at the location in the Landsat imagery, but the sand is so bright it is not possible to see whether the writing is still there. Let’s hope DigitalGlobe or another satellite imagery provider got a good image and we see it in Google Earth eventually.
It is not the largest artwork ever made with tracks in sand. That title, we believe, is held by Jim Denevan, whose Black Rock Desert piece we have looked at before. He apparently used a roll of chain fencing pulled around by a truck. Also featured in that post is the Mundi Man or Eldee Man by Ando, drawn in Australia using a tractor, but it is quite a bit smaller than the Hundai message. The Nazca Lines of Peru are much older and were created by removing reddish pebbles from the surface exposing the lighter ground underneath.
