We’ve had an explosion of Geckos in the house. They’re cute and they eat all the small flying bugs, but they fight with each other all the time, constantly chasing one another out from behind picture frames and hide-holes. This little guy had just won a ferocious battle. Go Gecko!
BTW this image is high res and will print well. It just looks pixelated because it’ll be printed so small on the T-shirt. When you view the Gecko full screen it’s enlarged so much that you’ll see the individual pixels that form the image, the enlargement having reached the point at which no further detail can be resolved.
