I like to poke my head outside of my own bubble and work on topics that I might not otherwise pick. I think that if you're going to keep your mind flexible the best way is to solve a problem someone else gives you rather than one you decide needs solving. Over in this thread, Nerdvana asked:
If you are still looking for something to do, a group mind ability (as discussed in this thread or the likes of the Tines from Vernor Vinge's A Fire Upon the Deep) would be intreguing. Basically a One Mind-Multiple Bodies issue. I had thought of Horde Intelligence but VickyM doesn't believe that would do the trick.
That's a interesting thought, how do you create a "one mind, multiple bodies" character? Well, Kromm came up with a useful method here. But that leaves the problem of the Ally/NPC angle. Basically, NPCs don't pay points for Allies, Patrons, Contacts, etc. and PCs don't pay points for PC allies either...or do they? Well, there are very specific cases where this rule simply does not apply and you might not even have noticed. This has been part of the design philosophy from Allie's inception (so I've been told) and I've personally always treated it as such, but for those needing a reference see GURPS Zombies (p. 50). This is clearly a case where Special Abilities is turning Ally into a supernatural ability versus a social one. In the same way that NPC wizards can purchase NPC familiars with Allies, so can NPCs purchase a ability to share one mind among many bodies. Kromm's method (and the best RAW model I think) boils down to:
Ally (individual of equal points; Constantly; Special Abilities, Can be played as PCs*, +50%) 
Mindlink (Allies) [varies]
Telesend (Racial†, -20%) 
* In effect, this Special Abilities enhancement lets you do what you like with the Allies, and is comparable to Minion, +50% in terms of waiving your obligations.
† "Racial" being used here as recommended for Duplication.
