Another viewer has done a portrait of our very own Professor Martyn Poliakoff - emerging YouTube superstar?
This one comes from Ellen Hong (aka @Sonnet_72)
When I asked to re-produce the picture, Sonnet said: "Sure, why not! I love your videos n' all staff members, especially respect him so much!"
I've posted a bigger version of Flickr.
And here are some earlier portaits of The Professor, also by viewers.
