One of the coolest things (I think) about being a designer - I love coming across unique ideas and uncommon shapes.
  

I will occasionally stumble across some unusual model here, on grabcad, 3dcontent central or elsewhere - something I might never have a particularly practical use in mimicking in my field of work, but I'll often download it anyway because I recognize that I can learn something new by studying it (and that's where the real worth is). 

I think off-the-wall ideas are also a great way to stoke up creativity.  (Another fun tangent might be - where have you  seen unusual or creative 3d models implemented in real life products or machine-equipment?)
 

I thought it might be fun to start a post where people share other quirky-but-skillful Solidworks models they've come across or created.
 

I'll start with two I've come across in the past -

One was a dodecahedron sphere, posted here a while back by ‌ :

Another one I came across (when I started becoming more interested in hobby cnc carved artwork) was done by

G Dmitriy V on GrabCad - https://grabcad.com/library/pano-carved-001-2 :

I thought his stuff was pretty cool.  I'm learning to use artcam to do design of this sort right now, but he parametrically modeled this in Solidworks using series of surface and knit features...and I've gotta say, for more elaborate designs like this - I think that is really impressive.
