An intriguing concept! Hopefully the Judges will not be looking for only images showing vast distances and not see the subtleties of interpretation of what 'Horizons' can mean. It looked like Danny's examples were mostly landscape horizons, which are inspiring, but by no means the only way to portray 'Horizons'. To portray more abstract concepts is definitely a greater challenge, one that I hope the Judges will understand and appreciate.
Softimage. Wow. Wasn't that a great program. Autodesk... I still have a working copy somewhere, alongside Mirai. Both were works of Art, and deserved better.
