A Katikati man's Sunday afternoon invention has attracted attention all over the world and is being used in the Johnson Space Center in the US.
Waikato University computer science doctoral student Paul Hunkin developed a computer software programme that's been picked up by Nasa and Google.
Mr Hunkin's software ClusterGL was created for the university's display wall in 2008 and joined multiple computers together to make one huge display screen.
After catching the eye of Google earlier this year, the programme is now being used internationally.
Mr Hunkin said there were five computers behind the Waikato display wall, with each computer controlling four screens. ClusterGL turned a display wall into one giant screen, by letting a single programme on one computer control all monitors.
