Code wanted!

[mvidas]

Thanks to PatrickAB who posted this question at EE, I thought I might share the same idea here Similar code to this is posted at that thread, but I purposely didn't finish part of it as a joke. I thought I might post my finished product here as a holiday treat for everyone, and to get everyone else's versions as well! If you're sitting at work and dont feel like actually working for a little while (as many people are at this time), its a great way to spend time and hone your excel skills as well
Anywho, heres my version, I look forward to seeing more!

Warning: don't stop the macro once the bulbs or star are flashing! If you do, say goodbye to that excel instance!
