The 'Guilielmus 010' is a picnic table design that appears to defy gravity. You might be wary about sitting on this table, which is understandable because it doesn't look like it should be able to stand at all. The table is cantilevered so that the weight is evenly distributed and able to function just like a traditional picnic table.
This design by Stijn Guilielmus Ruys gets rid of the supports under the table so people have more leg room when eating. Two of these sculptural tables could be put together to create a create a full-sized picnic table with extra seating. This striking picnic table and bench is like a piece of Escher's art brought to life -- it is as perplexing as it is beautiful.
