Why Glass Interfaces Made Us Feel Optimistic

For about six years, every screen looked slightly wet. Buttons had a highlight across the top. Windows had a shadow deep enough to lift them off the wallpaper. Somewhere in the corner, a bubble drifted upwards for no reason at all.

We called it a lot of things at the time, and mostly we did not call it anything — it was simply what a computer looked like. Looking back, the whole style was doing one job: making a machine feel like it was made of something.

Depth was a promise

A glossy button told you two things before you read a single word. It told you where to press, and it told you the press would do something. The highlight sat on top, the shadow sat underneath, and your hand knew what to do without being taught.

Flat design did not remove decoration. It removed instructions.

That is the part we lost. Not the gradients — the gradients were the fun bit — but the little physical hints that told you what was pressable.

Nature, but rendered

The other half of the look was the wallpaper: water, leaves, sky, the occasional fish. It was technology insisting that it belonged next to living things. Slightly naive, and I liked it.

Three things worth keeping

• Highlights on interactive things. One light edge is enough.
• Backgrounds with air in them. A soft gradient beats flat grey.
• Motion that is barely there. Anything that loops slowly reads as calm.

And three things to leave behind: the reflections under every word, the drop shadows on text, and the fifteen-step gradients on small buttons. We do not need to bring back the whole decade — just the part that made software feel friendly.

Next Sunday: the six gradients I still use, with the colour values.
