There were things that people called animated windows and animated icons at the time, but the meaning was quite different from what we think about today. For example: an animated window was an animation effect on the frame when a window was opened or closed, while an animated icon could be showing one icon for a closed folder and another icon for an open folder. (These recollections are from 1995 era OS/2. Windows had it's own stuff going on, but I pretty much ignored it from the introduction of Windows 95 until late Windows XP.)
