Yes, I remember using it, call for my dad while I was hiding in my room, he could see that I broke my monitor. :D

I thought of this the instant I saw the OP, I remember being in school and causing chaos with this, great memories.

Wow I just had a faint memory of this the other week! In particular, one of the stamps is a rabbit that I had the faintest memory of. Just did some digging and turns out it was from here: http://www.gemtree.com/

There's a Mac version too! https://simonbs.gumroad.com/l/smashsmash

I remember that. Someone hid the exe deep in my highschool's shared drive and renamed it "anti_stress.exe".

Oh wow that brings back memories. I remember playing with this back in my middle school days
