A kind nephew introduced this website and I think this programme is marvellous.
It show various well known things on Earth, as well as humans, and then, by moving the cursor along the bottom, pans out to show their proportions compared with the Universe.
This may sound rather dry, but the actual graphics, and the things chosen, look fantastic and have certainly shown me some relative distances and sizes that I knew absolutely nothing about.
The end result is to awe and wonder at the place we inhabit and puts some imagery on all those vast, and tiny, incomprehensible numbers we read about.
I hope you like it too. Enjoy:)
