Good for you! I've lost most of my "childhood coding" stuff to an accidental `rm -rf /home /something` (note the extra space. Backups? what backups?) some ~18 years ago. That included a couple of DOS viruses, one of which was polymorphic (I wrote them just for fun and never spread them; did upload one to an antivirus vendor BBS back then through their "Submit a new virus" function and it's still in many databases because of that); a C++ rewrite of mars.exe voxel landscape generator, but with added rotation, music and lakes; a PWM-based WAV player for PC speaker; etc. I'm still quite sad about that accident ...
