A stylized promotional flyer for OSSConf 2026 features bold geometric shapes, folkloric motifs, and a vibrant color palette inspired by Slovak modernist aesthetics. The central text “OSSConf” appears in large, white uppercase letters with a blue shadow, and “2026” is displayed below in bold green-orange numerals. The background depicts a stylized cityscape of Žilina, including church towers, colorful rooftops, and a futuristic train crossing an arched bridge over the Váh River. A cream-colored sky with a red-yellow sun and two folk-style birds adds warmth. The foreground includes a vintage computer with code, an open book with plant and gear illustrations, a satellite dish, and two figures—one using a laptop, the other observing. Decorative folk patterns line the bottom edge. The overall composition blends tradition and technology, celebrating open-source themes in a distinctly Slovak visual language.

Promotional graphic for the useR! 2026 Conference in Warsaw. On a black background, white uppercase text at the top left reads “USER! 2026 CONFERENCE WARSAW.” Centered lower on the image, the word “Tutorials” appears in large, bold turquoise letters, shifted closer to the bottom than in previous versions. Beneath it, a light blue sentence reads “The useR! 2026 Call For Proposals is open until March 8th!” On the top right, four square tiles display colorful fractal-style designs: blue, yellow, orange, and purple. Each tile contains a central black square surrounded by smaller squares in grid patterns, suggesting themes of data, computation, or modularity. The layout balances bold typography with vibrant geometric visuals to promote the conference’s tutorial track and proposal deadline.

A rectangular promotional graphic for the useR! 2026 Conference in Warsaw. The background is solid black, creating strong contrast with the text. At the top left, “useR! 2026 Conference Warsaw” appears in small white uppercase letters. Centered below, the word “Talks” is displayed in very large, bold white type, making it the dominant visual element. Underneath, a light‑blue sentence reads: “The useR! 2026 Call For Proposals is open until March 8th!” In the top right corner, four small squares form a 2×2 grid; each square contains a different geometric pattern in bright colors—blue, yellow, orange, and purple—adding a decorative accent to the otherwise minimal layout.
