Black Magic Design bought eyeon.
With eyeon it bought Fusion.

Now you can get Fusion 7 for free!!!
A high professional node based compositing program for free.Almost crazy.

Not so much limitations for a free version.
No Network rendering and 3D stereo stuff and some high advanced features.
That's it.
Fusion7 Studio is now down to 999$

This is a canon blast in "The Foundry" direction. Never played with Nuke, all say it's the best, but hell, that's an expensive piece of soft.

In the same order of idea : Natron! (A French product in English

I will take a look too in the next time, they are booth alternatives for AFTER EFFECTS? And how hard is to learn these programs?

And in 3D, I have to forget to say, that I'm a Silo fan, a little bit disapointed of Nevercenter, because this very sweet subdivision modelling-tool but very sadly silo-users did haven't had an update for years. Since some months there is an update 2.3 - hope that silo wil have a nice future too?

And 2D?
Ohh, I have now MISCHIEF too, I took it for 25,-USD - very great for LINEWORKS and in future for more - good companion for verve, it works ver fine with LAZY NEZUMI too

And next days I will have a nice GTX 970 I hope ... if dear Taron made a nice Update of Verve until CHRISTMAS it would be so fine ... a very great start for 2015

Ahhhh Silo.. totally my favorite box modeler that seems to have been swept under the rug and into the grave let us pray lol I hold small hopes for it Zero

I have hope, because it is alive - http://forums.cgsociety.org/forumdisplay.php?f=175 - hope ther will be 64bit Version soon and some bug fixes ....

In box modeling you have the incredible Wings3D + the manifold Lab plugin!

EDIT!
Only free Programs, no shareware, no trials.

There is a free version of mischief too.

Lazy Nezumi works even in 3D Space, e.g. in 3DCoat I will test it also in other 3D Apps, if I feel some needs there - maybe also in moi3d for drawings curves? I will test
