While digitally enhanced to add more balls and smooth out imperfections, the core of the ad used practical effects, relying on the natural bounce and movement of the balls. Its production involved meticulous planning, street closures, and the collaboration of numerous artists and technicians. The ad became a sensation, boosting Sony's brand and inspiring numerous imitations.
HN commenters largely discuss the effectiveness and memorability of the Bravia ad, with many recalling it vividly years later. Some analyze the technical aspects of its production, noting the lack of CGI and the challenges of shooting with 250,000 bouncy balls. Several compare it favorably to modern advertising, lamenting the perceived decline in creativity and impact. A few users question the practicality and cost of the ad, while others share anecdotes about similar projects or express skepticism about its authenticity. The overall sentiment is one of appreciation for the ad's unique and engaging approach.
"Flow," an animated short film created using the open-source software Blender, won the Oscar for Best Animated Short Film at the 2025 Academy Awards. This marks a significant milestone, being the first Oscar win for a film primarily produced using Blender. The film, directed by an unknown director, explores themes of environmentalism and the interconnectedness of nature as it tells the story of a plastic bottle's journey through a polluted waterway.
HN commenters were impressed with the technical achievement of Flow winning an Oscar, particularly given its creation using Blender, a free and open-source software. Several pointed out the democratizing effect this has on animation, making high-quality production more accessible. Some debated the film's artistic merits separately from its technical ones, with some finding it derivative of Pixar while others praised its unique style. A few commenters speculated on the future impact of this win, predicting an increase in Blender's adoption and potentially a shift in the animation industry towards more open-source tools. There was also discussion about the challenges of using Blender for large-scale productions, with some noting the need for robust pipeline tools and experienced users.
"HTML Kaleidoscope" is a simple webpage demonstrating the creation of visually appealing, kaleidoscopic patterns using only HTML and CSS. By strategically layering and rotating multiple copies of a basic SVG graphic within nested divs, the code generates a symmetrical, colorful design. The effect is further enhanced by applying CSS transforms and animations, causing the pattern to dynamically shift and rotate, creating a mesmerizing visual experience. No JavaScript is required, showcasing the surprising power and flexibility of pure HTML and CSS for generating complex visual effects.
Hacker News users discussed the visual appeal and technical implementation of the HTML Kaleidoscope. Several commenters praised its aesthetic qualities, describing it as "mesmerizing" and "beautiful." Some delved into the code, noting the clever use of CSS and JavaScript to achieve the effect, and appreciating its simplicity. A few users pointed out similarities to other kaleidoscope generators and suggested potential improvements like adding color controls or different symmetry options. Others expressed a desire to understand the mathematics behind the kaleidoscope's reflections, while some simply enjoyed the visual experience without analyzing the technical details. Overall, the comments reflected a positive reception to the project, with a mix of appreciation for its artistic merit and technical ingenuity.
Post-processing shaders offer a powerful creative medium for transforming images and videos beyond traditional photography and filmmaking. By applying algorithms directly to rendered pixels, artists can achieve stylized visuals, simulate physical phenomena, and even correct technical imperfections.
