One great tool for making visualizations of DEMs derived from lidar point clouds is Aerialod. Lots of options to render 3D models in different lightning. In the new 0.2 version, we have RGB overlays! Stonehenge landscape 3D render.

One of my favourite archaeological sites. Prehistoric and late antiquity hillfort Ajdoščina above Rodik, Slovenia. Most archaeological features visible on lidar visualization are from the late antiquity phase (4-6 century).

I am a landscape archaeologist and my specialization is the usage of lidar data for archaeological purposes. You will see me post some visualizations of archaeological sites, especially hillforts. And cricket stuff of course. #FridayLiDAR An image of Cadbury hillfort in the UK.
