As LEGO fans across the world celebrate the 60th Birthday of the LEGO brick, in the heart of Denmark, a very special celebration is taking place at the LEGO House in Billund. A number of fan builders have put their build skills to the test to create a variety of brick-built clocks each showing the exact time the LEGO brick patent was issued. These clocks are all on display in the LEGO House and you can see some of them below, thanks to pictures taken by Jan Beyer from the LEGO Group. As well as these impressive timepieces, visitors to the LEGO House today will be able to join in the celebrations and partake a some free cake.
