With enough Blu-Tack you can do anything
In true MacGyver fashion, I've used two strips of Blu-Tack to stick my Air Force HALO Jumper figure to the top of my monitor.
He has a pole sticking out of his penis which is meant to jam into a clear base plate, but that's not very exciting.
Instead I stuck the pole to the back of the monitor with way too much Blu-Tack.
The other option was to hang him on some fishing line from the ceiling, but then he'd be spinning around and distracting me.
I'm half-expecting that he'll be lying crumpled on my desk tomorrow morning.

so, verdict - was he on the desk crumpled? or did your blu-tack mastery keep him up?
