I like this. Definitely unusual. Not sure I would use it on my desktop - can't quite imagine how it would look - but maybe. I certainly like it a lot. I like the contrasts you have going here - almost wood and then something like coloured glass, with different colours melted and stirred together to form panes like marbled paint...
Again, you have me scratching my head as to the how ... you are going to have to solve the 'mystery' for your viewers in your next pieces' accompanying narratives. ;o)
As a suggestion, this style would lend itself to a revisit in my mind. As I could see creating another wherein the coloured tiles form a composite overall.
This is certainly 'fresh', and fresh ideas are certainly welcome in my books. Nice work here.
Thanks!
