Thank you British Medical Journal for featuring First Do No Harm in this week's edition.

I've put some nests in the Tanera exhibition, and I realise I'm far from being alone as a human nest builder -

This stunning (and presumably strong) artist-made nest is by Benjamin Verdonck.

If you visit his site to enjoy the  journey, you might possibly need to be a bit patient with the technology. It's worth it though. Do lots of inquisitive clicking along the way.

Ingredients for this recipe are:

• cartridge paper
  
• quink ink (must be a washable variety of ink anyway)
  
• sandpaper to rub  back the surface after drying
  
• a pointy stick, or an old brush
• household bleach
  

...and off you go drawing. Maybe wear goggles if you are going wild with it. 

The area where the bleach hits turns a beautiful golden colour. The turquoise in the drawing above was a layer of acrylic ink, added to see if it bleached. It didn't.

From Danish artist Peter Callesen.

A fantastic resource book from Black Dog Publishing.

From the same book, Rob Ryan's work can't but bring a smile.
