Basically they are highly articulated (hence the "Artifigure" neame) yet relatively sturdy figures shaped around a base body.
They do appear somewhat bulky due to the joints, so armored characters will work out better.
So building a Boba Artifig, I realize how many parts in correct colors I lack (many not even being produced in the required colors) so I decided to round up old parts I don't use, such as the light gray, replaced by the light bluish gray in 2004, and then chose to paint it more or less realistically.
Mind that I only have these production shots, I managed to cover the model in too much sealant resulting in a far too thick layer, obscuring the color and texture.
So these are probably the best shots there will be of this one.
That said, here you are:
LEGO Boba Fett Artifig
Here he is posed after the added sealant, which as you can see leaves a thin white layer to it all
I have plenty of other characters constructed and under construction, based on other themes and characters, and some original designs.
I will probably put up one or more LEGO CUUSOO projects for Artifigs, given there is a genuine interest for it.
And for those interested in building instructions, I will come back with some soon enough!
Here are some of my physical in progress creations (I have several digitally designed ones as well).
From left: Artifigure "Proto Skeleton", Boba Fett RotJ (Existing colors), Boba Fett RotJ(Painted), Gabriel (Character from Dan LuVisi's Last Man Standing) and Metroid's heroine Samus Aran!
Additionally I have one of my most recent designs, simply a robotic drone character with great articulation, able to strike plenty of highly dynamic poses with elegance.
I hope you found this interesting, I myself am utterly amazed with articulated figures, which is the reason I even ended up creating these LEGO Artifigures.
It's a thing I would love to see being produced by LEGO themself, coming in neat palm sized boxes with appealing cover art.
These would naturally be aimed towards more mature builders, as they aren't constructed to withstand play in the same way Bionicle or Hero Factory figures have been.
The idea of Artifigures is oriented towards a new range of dynamic LEGO models, perfect for displaying your favorite characters in whatever pose you desire.
