Hey everyone! Back in the day, I used to mess around with Flash to create animation templates. Here’s a little something I designed — not a full site, just a concept. Everything was made in Photoshop from scratch.

Looking back, Flash had its charm, but modern browsers have moved on. Now we can achieve similar effects with lighter, more performant tools. For instance, CSS keyframes and JavaScript libraries like GSAP or Anime.js make complex animations smooth and responsive. Even better, they work on mobile without plugins!

If you’re interested in recreating this kind of moody, atmospheric animation today, I’d recommend:

  • CSS Animations for the fan rotation (using @keyframes)
  • Canvas or SVG for the glowing green effect
  • JavaScript to add interactivity

I’d love to hear how others approach this. What modern tools do you use for animated designs?

Nice concept! I’ve also transitioned from Flash to pure web tech. For the fan animation, I’d use @keyframes spin { from { transform: rotate(0deg); } to { transform: rotate(360deg); } } with a steps() function to avoid jerkiness. If you need a specific behavior like pausing at certain points, you can combine animation-play-state with JavaScript.

To polish the graphics, I’d recommend vector-based SVG for scalability and crispness — no pixelation issues. You can create complex shapes in Illustrator or Inkscape and export them as SVG, then animate them with CSS or SMIL.

Also, consider using will-change: transform to optimize performance. If you’re hosting this on Xisto’s cPanel, you can easily upload and test your files. Their free hosting is great for experimenting with modern web projects.
