iglass
The fact that someone built a liquid glass effect for iTerm2 and Ghostty tells me more about developer culture than the tool itself. People will absolutely spend an afternoon tweaking the transparency and blur on their terminal before they write a single line of code. That's not a criticism. The terminal is the most personal piece of a developer's setup, and tools like iglass are catering to that identity.
I find it interesting that it targets iTerm2 and Ghostty specifically. iTerm2 is the old guard, the default for macOS users for over a decade. Ghostty is the new kid, built by Mitchell Hashimoto, and it's been picking up serious momentum. Supporting both out of the gate is a smart play. It says the creator understands that there's a big audience of people who won't leave iTerm2, and an eager crowd who already jumped to Ghostty.
Where I land on this is simple. It's a niche tool, sure, but niche tools with strong aesthetics have a way of becoming the default. The liquid glass effect is the kind of thing that looks great in a screenshot, and screenshots drive adoption. I'd want to know how it performs under heavy terminal load, whether the blur tanks performance on older Macs. If it's smooth, I could see this becoming a must-have. If it stutters, it'll be a fun experiment that fades fast.
