Product news: this wind-up toy by British design brand All Lovely Stuff creates abstract art when let loose on a sheet of paper.
Inspired by the cotton-reel tanks they played with as children, All Lovely Stuff designers Ed Ward and Carl Clerkin adapted the mechanical toy to hold a felt tip pen.
To propel the machine, simply wind the cotton reel while holding the wax cylinder, then place it down and let go. The height and position of the pen can be adjusted to make bigger or smaller circles, or straight lines.
The machine comes in a self-assembly kit containing an oak cotton reel, a clothes peg, a felt tip pen, a rubber band, a dowel and a piece of wax, and is available online from All Lovely Stuff.
Earlier this year Dezeen filmed a movie with designer Carl Clerkin, who told us about his aim to create functional wooden products with "a little bit of charm about them".
Other machines we've featured on Dezeen include a rotational moulding machine that inserts spontaneity into serial production and a contraption that mimics birdsong – see all our stories about machines.
We've also featured lots of toys on Dezeen, including wooden toys that incorporate plugs and clothes pegs and a knitted tree filled with knitted creatures.
