What’s your opinion on gamifying software development work?

This is going to be a bit meta but I'd love to get some opinions on this.

Can you / should you gamify software development work? Let me clarify this with an example:

– You were at your desk before 9 am for 10 subsequent days (100 points)

– You shipped code for 5 subsequent days (100 points)

– You completed a code review (50 points)

The goal of this would be to nudge people into a more effective way of working (shipping often & fast, being on time, etc.). The points could of course be redeemed for something you'd like.
