SilentMode's Creations.
The mainstream LEGO space calls them MOCs (My Own Creations), and once upon a time I used the term "SilentMOCs".
Either way: since my introduction to the hobby in 2010, I've designed, built and made what I now just call Creations.
I don't limit myself to plastic bricks: instead, I make use of 3D printing, resin casting and other techniques, exploring "LEGO-inspired design".
