Possibly my most complicated miniature painting so far. It reminded me that I have an opticians appointment on Friday 🧐🤭

Freeing the Spirits of the Sea
This digital painting is set on a rocky ocean shore. The sky is dark and stormy. The environment is very cool and blue. A girl with black and white hair, wearing a spotted dark-purple cloak, is summoning sparkling, ghostly whales and sea creatures from the ocean. She stands on a rock, lit by the yellow sparkling creatures above.

Digital illustration of two ghosts in front of a red pagoda sitting on the water. Behind them is a lilac and pink sky with the sun setting. Above them is a cherry blossom tree and pink lanterns hanging from the branches. Digital illustration of two ghosts facing each other in a sunflower field. They are floating above the flowers in front of a blue sky. The ghost on the right is holding a sunflower out to the ghost on the left. Digital illustration of a ghost and a glowing jack-o-lantern huddled under a clear umbrella. They are standing at the base of a lush forest in the rain. The leaves around them glow orange from the light of the pumpkin. Digital illustration of a ghost sitting on a bench holding an orange autumn leaves. Around them the leaves have turned orange and yellow. There are birch trees behind them. The ground is wet and reflects the bench. There is one floating leaf in the foreground, surrounded by many other fallen leaves.

La resonancia es cuando dos cosas vibran al mismo ritmo 🎵. Ocurre cuando una frecuencia externa coincide con la natural de un objeto, amplificando su energía. Es la magia donde ciencia y música se encuentran: todo vibra en armonía. ✨ #Ciencia #Resonancia #Educación

Que es una opera?
Vámonos primero a la definición formal:
Una opera es una representación escénica teatral en la que una acción se canta por medio de uno o más personajes teniendo un acompañamiento musical.
Esto, por si solo, nos da una idea, pero, seamos sinceros, no aclara mucho. (1)

Animado por el hilo de @anlaetificat.bsky.social sobre notas y frecuencias, aquí va otro muy relacionado sobre la riqueza tonal en la música árabe. O también: qué es una nota en la música occidental vs qué es una nota en la música árabe.

¿Sabías que la nota "La" (A) que usamos para afinar no siempre equivale a 440 Hz? En música antigua suele bajar, en muchas orquestas modernas sube, etc, y esa elección cambia color, tensión y sensación en la música.

Ven, ven, que cuento por qué dos orquestas tocando lo mismo pueden sonar distinto.

Buenos días. Hoy 29-O hace un año de la DANA, barrancada del terror. De las marchas del barro, los corazones rotos, la impotencia, desesperación, la incertidumbre, el horror, el caos. Y también de un pueblo resiliente que se levanta desde el fango gracias a las manos amigas de paisanos y extraños❤️‍🩹
Coches apilados llenos de barro y debris bloqueando una calle entre fincas El puente de la solidaridad, con una marcha de gente volviendo a casa tras ayudar en zonas dana Botas, piernas y ropa llenas de barro Una calle del barrio Orba (Parque Alcosa) con trastos y barro apilados. Las fincas son bajas, la gente trasiega arriba y abajo la calle.

Gotta share here this SUPER COOL panel @noiry.bsky.social did for my FMP! extra comic "Love Bites", impossible to think of vampire hunters without remembering Castlevania, which is why I asked the artist who could pay the greatest tribute to the saga, and my jaw is still on the floor! THANK YOUUU!

"How large is your artistic range?"

Me: " Yes "
The retro-futuristic image depicts a cyborg figure rendered in cool blue and white tones. The creature has an abstract, geometrically simplified face and body, and is dressed in a sleek suit with a triangular blue pattern on the chest and belt. Lines reminiscent of cables extend from the head. At the bottom of the poster is the inscription: "THE AVANGARD INITIATIVE" The background is dark and contrasting, with clean, straight lines and an Art Deco-style frame, creating a striking effect. A black-and-white illustration executed in a fine line drawing technique. The composition is a fantastical landscape, combining natural and architectural forms. In the center of the image is a large circular structure, resembling a giant arch, composed of numerous intersecting straight lines and geometric elements. The lower portion of the drawing is filled with dense, wavy, and mosaic-like patterns reminiscent of earth, roots, or streams. In these areas, the lines become sinuous and organic, transitioning into dark textures with dots and hatching. A light background with clouds is visible on the horizon.
