Akorát mi tak přichází na mysl, a nemohu na to přijít ... k čemu je KU..A na hrnci dobrá WiFi ...

An incredible display of #LightPillars last night here in -20°c #Sweden. Stretching right to the zenith from all around, see the photo looking straight up at the converging pillars!

Just before Christmas, I finally put up the amazing Fibbinocci spiral flower light sculpture that I got from @evilgeniuslabs.org. Visitors to the house have raved about its patterns and how it adds a pleasant accent to our family den.
