Design an image of a clean and futuristic, technology-centric background transitioning from deep blue at the top to black at the bottom, embedding subtle circuit board patterns that hints at technological complexity. The center visual, a large glowing futuristic padlock, will symbolize the security with semi-transparent circuits and connection nodes radiating from it to represent network connections and remote access. On the left of the padlock, include a glowing stylized symbol that resonates with encryption, while on the right, a symbol that signifies a tech-assistant software. Quietly situated in the top background, place an icon to signify remote access and cloud environments. Lastly, subtly scatter futuristic key icons in the background, signifying authentication protocols, and apply soft glows and neon-like highlights around the elements, coupled with subtle drop shadows to impart them a high-tech and a 3-Dimensional look. The final layout will have a deep blue hue at the top with a circuit board pattern and a cloud icon, the center will have a large glowing padlock with radiating circuits, flanked by the stylized encryption and the tech-assistant software symbols, and the bottom will be a dark gradient fading to black with additional authentication key icons.

SLUUG - June 12, 2024

Design a vibrant collage-style image that visually represents the concept of social media for a tech-savvy audience. The main background should be sleek and modern with a gradient from a dark to a lighter shade of blue or green. Incorporate various logos: a simple 'M' with a mammoth mascot, a colorful hashtag-like symbol, a game controller with eyes, a recognizable TV network logo, and a purple speech bubble with 'Live Stream' spelled inside. Arrange these logos in a circular or scattered manner, equally sized, around the center of the image. Enhance the techy feel by adding semi-transparent icons of computer-related items like code snippets, circuit boards, or network symbols into the background. Ensure a cohesive color scheme, incorporating shades of blue, green, and purple that complement the logos. Apply a gentle glow or shadow effect around the logos for depth and add light flares in the background for a dynamic, modern feel.
