Regular readers of TIR may have noticed that there’s been a change in the visuals of late. Besides my own rather staid photography, there’s been an increasing number of contributions from the marvellous Oliver Hoeller, a scientist and freelance illustrator. I’m now delighted to announce that Oliver is officially joining TIR as its “artist in residence”. A short bio and links to some of his other work can now be found in the “Artwork” tab at the top of the page.
