I remember hearing about a few of these back in the day, but I never knew it was a full-blown community. This gallery at The Apple Collection has a ton of great aquarium mods for classics, old iMacs, and… is that a Newton?

All the tutorials seem to have had their hosting pulled a long time ago, which speaks to the timeliness of this post, but anything’s possible with bit of caulk and some time on your hands. Be sure to tell your friends that out loud, they’ll appreciate it.
