October at the Baltic coast. Autumn starts slowly this year #silentsunday #photo #balticsea #ostsee
Baltic coast imaged as four horizontal layers: wild roses, a dune grass, water and the cloudy sky.

Hmmm, I'm starting to think that a deep sense of wonder at the beauty of the universe, expressed through art or the spiritual #transcendence found in religion, will be our weapon against the AI pushed by #techbros. We are the only beings in the known universe capable of that.

Wczoraj zrobiliśmy sobie wycieczkę rowerową wzdłuż Piany i nad niemieckim Bałtykiem. Przepiękne szlaki rowerowe. Największą dumą z naszej pięciolatki, która dała radę przejechać ponad 20 kilometrów. #Rowerstwo #silentsunday #Cycling

Po siedmiu latach powtórzyliśmy rodzinny urlop w austriackich Alpach i nad chorwackim Adriatykiem. Najpierw wędrówki po szlakach, później leniuchowanie na plażach i kąpiele w ciepłym morzu. Tym razem z dwoma córkami. Polecam wyspę Lošinj, trochę poza szlakiem, bez molochów hotelowych.

Wild beach on north of Rügen, largest island on the German coast of Baltic see. #silentsunday #photography #beach #baltic
The Baltic Sea is on the left and a stony beach with small stones and large boulders is on the right. On the far right, there are plants and branches emerging from the beach. In the background are white cliffs partially covered by a green forest. The weather is sunny, with just a few white clouds on the horizon.

I went for an early walk in the forest not far from my house and tried to photograph some birds. Only partially successful. In the middle, I enjoyed a quiet breakfast. The carpet of thousands of anemones always looks so wonderful to me. #SilentSunday #photography

We took a family trip to #Jasmund National Park to look for the first signs of spring, but spring was still shy. This is my favorite place on the German Baltic coast. #silentsunday #Vorpommern #ostsee #baltyk
Blue water of Baltic see on the left, vs white chalk cliffs on the right. Still no green leaves on the trees covering the cliffs. A leafless tree  growing out of water, its reflection clearly visible on the water surface.

With the new kitchen CD player I am rediscovering my own CD collection. Tonight - Fish and “Vigil in a wilderness of mirrors”. Very good record, the first one after Fish left Marillion.
Hardcover CD/book set of Fish’s “Vigil in a Wilderness of Mirrors – 2024 Remix” lying on a wooden surface. The cover art shows a surreal, colorful scene: a cloaked figure standing on the hood of a car covered in red roses, with stylized clouds and jets in the sky behind them and flowing fabric billowing to the right. Along the bottom edge, several small TV screens display blue‑tinted portraits, while the artist’s circular Fish logo appears at the top center above the album title.
