## Tube map Platonic solids, pt. 2

Following my previous post, I did a little more folding.

The post was linked to on Going Underground's Blog where it received this comment:

In response to which I made this from 48 tube maps:

Also since the last post, I left 49 tetrahedrons at tube stations in a period of just over two weeks. Here's a pie chart showing which stations I left them at:

Of these 49, only three were still there the next time I passed through the station:

Due to the very low recapture rate, little more analysis can be done. Although I do wonder where they all ended up. Do you work at one of those stations and threw some away? Or did you pass through a station and pick one up? Or was it aliens and ghosts?

For my next trick, I want to gather a team of people, pick a day, and leave one at every station that day. If you want to join me, comment on this post, tweet me or comment on reddit and we can formulate a plan. Including your nearest station(s) in your message will help us sort out who takes which stations...
