The Virtual Museum is best viewed with a free plugin called PicLens. 
This gives you a really cool view of a 3D wall full of images which you can click on or view as a slide show. Just click on the "See this in 3D" or "Get PicLens" links and follow the download instructions. You will need to exit and re-start Internet Explorer and navigate back to this page, but it's worth it! Thereafter, PicLens will be installed for all other websites using PicLens, so you only have to do this once.

Once you have PicLens installed, you can click on "Start Slideshow" and the 3-D wall will appear. You will see a blue-dotted slider at the bottom of the screen - slide it to the right or left and the wall will scroll by. You can click on any picture to enlarge it, then click outside to close it. You can also click on the Full Screen icon (it has arrows going outwards) and scroll through the images or start a slide show. Experiment with the buttons - and have fun!

Clicking on the X at the top right of the screen to come back to this webpage.
