As a LEGO Certified Professional, I mainly commercialize mosaics: studs up our out, Black and White or Full Colour, small or large: you name it. The largest one so far is this LEGO cow, measuring 2m x2m. It was made for an event called "Mechelen Speelstad" (Malines, City of Toys) in May 2009.

When Jamie Lidell came to a TV show in Belgium, I was asked (just two days on beforehand) to make him a LEGO gift. Apparently Jamie is kind of crazy about LEGO just as much as I am.
I celebrated my 40th birthday with a huge theater show in Antwerp. Many other celebreties joined the show. We sang together, did sketches togeteher, and so on. In stead of giving them a bunch of flowers after their act, I gave them their head in LEGO mosaic (one base plate, studs out)
