On the main site when one navigates to the view URL of a synth which is still in the process of processing/uploading, one is presented with the message:
"We’re working on it!
This Photosynth isn’t available yet. Please check back a little later. If it’s already later, things must be really busy."
On the Preview site, when this is done, one is presented with the message:
"Can't find this synth
Sorry, but this synth is no longer available. Explore other amazing synths and learn more about Photosynth."
Updating the copy to reflect that the URL is correct and the synth should be available there in the near future would be appreciated, much the same as a video's page on Vimeo or YouTube when the upload is in progress or you are waiting for the the site to transcode the video for web viewing at multiple resolutions/bitrates.
