They're getting on so well together! Tee-four (the phage on top) was a present from Genetic Inference And Colin (the rather worried looking E. coli underneath) was actually a long-ago present from Paradigms as well.
Many apologies to Genetic Inference for taking so long to realise who tee-four was from. I've been neglecting the Internet in general lately to try and encourage me to revise more :)
