In the example I have mentioned before, there is nothing of visual interest in the Highlights and the url in their description only serves as a jump to a next synth, because there was insufficient overlap for synthing them together.
Meanwhile, in another synth, I have created a Highlight, highlighting a statue with in the Highlight's description the name of the statue and the url to the Spin synth of the statue.
If I have finished playing around with this, i.e. have created some examples, then I will post the url's in this discussion. I hope others will join and that the conversation will help the team in improving direction on this.
