There is always pressure on the reams of travel content sites on the web to find new ways of keeping visitors interested, but thankfully new methods come along almost constantly.
Take this intriguing effort from a group of developers in Hungary...
The Billion Pixels Budapest project is a simple system where users can zoom and out of a high-resolution image of the Hungarian capital to view famous landmarks.
Part of the 360-Degree World programme, the idea is to show buildings strewn across the city in context with their surroundings, more than anything else.
Although at this stage there is not much else the user can do with the system, integrating it into a destination site with detailed information about the items on view would certainly capture the imagination.
Second Life and other virtual worlds may not have hit the mainstream to the extent (or at all) as perhaps their backers envisaged, but still the application of the concept seems to intrigue destination marketers.
A service known as Twinity is trying to bring the idea of virtual worlds to tourism boards in a more engaging way, allowing visitors to get a sense of what is on offer and learn more about a particular service or activity in a location.
Here is how a clip that accompanies an interactive travel guide to the Berlin Wall in the German capital:
