By far my favorite is the temporary installation on the Isle of Tyree in Scotland. It just looks so magical.
" You might go hunting for treasures but you generally happen upon them during your adventures or casual interaction with the environment. I enjoy the fact that many people will not notice these, but some astute people will; that these will not last forever and the weather will affect them as naturally as it might in nature."
“Watch Your Step” examines the relationship of the work to the floor and how the viewer experiences the work, shifting one’s perspective from eye-level to start from the ground. Various works emanate directly from the floor, while others use the space between ground and wall to increase one’s perception of the horizontal plane and the architecture. "
"My work illustrates a fantastic landscape. It represents nature's subtle way of dealing with the peculiar aspects in the relationship with mankind. A giant glow-in-the-dark heart, or a pile of precious gems tells us that we are loved, just as blood squirting from an oak tree trunk says, all is not well. I am inspired by my conversation with the landscape, I imagine long monologues when pine forests make me laugh and mountains test my patience."
