  For the Royal Society Summer Science Exhibition 2016, the Institute of
Computational Cosmology from Durham University created the Galaxy Makers
exhibit to communicate our computational cosmology and astronomy research. In
addition to the physical exhibit we created an online component to foster
re-engagement, create a permanent home for our content and to allow us to
collect the ever-more important information about participation and impact.
Here we summarise the details of the exhibit and the successes of creating an
online component. We also share suggestions of further uses and improvements
that could be implemented for online components of other science exhibitions.
