\section{These problems were tackled at HealthHack 2013}  \subsection{I want to display a heap of genetic information at once…}  We need a simple and highly visually effective software package to display genetic and epigenetic marks, where we can view many different layers of information at once, and easily switch between viewing a single region of one gene, to viewing many genes, to even viewing a whole chromosome.  There are many publicly available datasets that could be used to create such visualisation software, and it would be worth considering the currently available systems for viewing such data (e.g. Galaxy, UCSC Genome Browser, IGV, SeqMonk). While each of these has its benefits, none provide a holistic view of the data that allows optimal visualisation. *Every cell in the body contains all the genes of the genome – the entire DNA content of a cell – but not every cell in the body is the same. For example, a heart cell is very different to a neuron. How can these cells be so different if they all contain the same genes?
