Today, when hundreds of paper boats will be launched by school children on Clydeside in homage to the artist, more details of the plans of the George Wyllie Foundation have emerged, including the creation of a museum in his name at the Long Room at Greenock's historic Custom House.
The foundation has already received £200,000 from an anonymous donor to buy key artworks that will form the basis of the Wyllieum.
The foundation also hopes to negotiate agreements with major art institutions to develop a range of exhibitions from next year, with partners including the Richard Demarco Foundation, the Summerhall venue in Edinburgh, and the National Galleries of Scotland and the Tate.
It is hoped the museum would launch with a three-year programme of exhibitions and education events, and raise income from Wyllie-related merchandise.
The foundation hopes to store his works, many of which are very large, in the Summerhall venue in Edinburgh, which has been in the news this week for its tussle with HMRC over tax bills.
The plans, still in their early stages, are being considered by the trustees of the foundation, who include Julie Ellen, director of the Beacon Arts Centre; Ronnie Garrity, a musician and businessman from Greenock; Calvin Gomes, an artist and George Wyllie's grandson; the filmmaker Murray Grigor; Lynne Mackenzie, curator of the George Wyllie archive and RGI Kelly Gallery; the MSP Joan McAlpine, the artist's daughter, Louise Wyllie, and other friends and supporters.
Wyllie, who died in 2012, aged 90, most notably created the Straw Locomotive in 1987, the Paper Boat in 1990, and the Running Clock outside Glasgow's Buchanan Bus Station, and has been lauded as one of the most influential Scottish artists of the past 50 years.
Today, schoolchildren, who spent the last six months of 2012 studying the artist's work, will launch a flotilla of paper boats.
The launch of the boats - called The Origami Fleet - was due to take place on Hogmanay last year at the Riverside Museum in Glasgow, but was postponed due to high winds.
Wyllie launched a huge Paper Boat on the Clyde in 1989, as a statement about the decline of Scotland's shipbuilding industry.
The self-taught artist spent time in the Royal Navy before embarking on a career as a Customs and Excise officer.
He moved to Inverclyde in the late-1950s and in-between keeping watch for ships to come into the docks in Greenock from his house overlooking the Firth of Clyde, he "made time for art".
The paper boat fleet will be launched at lunchtime today at Custom House Quay, where Wyllie worked for many years.
Foundation trustee Jan Patience said: "We are delighted this launch is finally taking place.
"It feels like there has been some cosmic intervention from George.
"Being able to launch the Origami Fleet in Greenock, at the place where George lived and worked, is much more appropriate."
