Maastricht, Netherlands LEGO enthusiast Berthil van Beek has created an incredibly complicated machine, known as a Great Ball Contraption, out of LEGO that continually accelerates small LEGO soccer balls and basketballs through a winding roller coaster at 1,000 RPM. It is an amazing recreation of a marble run originally designed by Akiyuki.
