This photo shows the black sand of Tenerife. The colored ones might be fragments of colored glass or stones, each piece of approximate 1 mm in size. What seems to be nice and colorful from the macro perspective, becomes a monochrome “black” (indeed dark grey) beach if observed from a greater distance.

Mystery Castle is part of the theme park Phantasialand. In March, Phantasialand becomes JavaLand . The photo shows the tower of this castle during sunset of December. I’ll talk about the upcoming Java Shell and show its integration within NetBeans on March, 29th. Visit my talk at high noon in room Quantum 3+4.  javaland.eu
