Lego has been trialling some new bricks to help children with sight loss learn to read.
Children at one UK school have been testing them out. Some say other approaches should also be taught.
You might think it is child's play - but plastic bricks are being credited with reviving memories in elderly care home residents in Manchester.
Lego therapy is helping people to re-discover communication skills and encourage them to socialise.
The activity is being held in one home in Blackley.
Resident John Parks said: "I'd like to build a Lancaster bomber."
Therapy using the popular toy is helping care home residents' communication and socialising.
The project for children at The Hollies School in Cardiff aims to boost their social skills.
A life-sized model of the Slade frontman Noddy Holder, made out of 42,000 Lego bricks, has been installed at a theatre in Birmingham.
Originally placed at New Street station over Christmas, it was commissioned by the city's Retail Business Improvement District (BID).
Organisers say, while at the station, it raised more than £4,600 for the Birmingham Children's Hospital Charity.
Now, it's been moved to the Alexandra Theatre's main foyer where the BID says it'll still be used to fundraise for the charity.
Schoolchildren took part in the Institution of Engineering and Technology event in Bristol.
