I was joking in 2007, when I was working at Siemens, to my boss, that an Excel cell can contain God and the Multiverse when I put an ActiveX inside that was basically a program I made which would draw a 3D animation based on parameters contained on other cells. Let's say the boss was impressed though for me was just basic OLE.

I see from time to time that younger generations reinvent/rediscover the wheel and I chuckle.
