Hi 3D Frog...
I started with TS when I was very young... My father was looking tools to create artworks (2D and 3D) then he found TS 3.2 downloaded the free version and starting messing up... He doesn't have much time to learn then he just stop, and say to me that if I want I could use, etc. I start using just doing balls jumping (with physics), crazy booleans (subtract it, add that and subtract it), I was learning very slow, but was fun! I loved the metaballs was funny messing up and doing objects with that, my first good creations is made with metaballs. 3.2 is very simple to understand so after 2 years (10 years old) I start developing good objects... I created I ''game'' I called it NASA 3000 (I love the space and start learning it when I was 6) the game uses what I call ''Manual System''

you tell me: I want to put my Space bus there, I put it make a subtraction of the money in a calculator and put the current money in the Notepad...
Then the demo of 6.6 appeared I got it and have a shock

why so many buttons??? How can I do what I do in the 3.2 version??? Well time pass the 7.6 become free in the start I used the 3.2 instead 7.0, then I talk with my self IT'S now or never and stop using the 3.2 and just using the 7.0 to see if I learn something in the first months nothing special then I given up... Some months ago I returned and now I'm much better!!! Thanks for all who helped me and the tutorials... When I returned I entered in the Caligari forums to rejoin the community and participate of the projects... Then I discovered that Truespace is dead

and then I discovered this community, from this point you know the history... XD
You can see some good arts made by me between 9 and 11/12 years old here:
vi ... ?f=6&t=489" by far my best is the X-Wing (I was not fictionalized in Star Wars but is a cool subject to make in TS).
My advice about your nephew is: Show to him Truespace as a toy and not a tool, because truespace is a fun thing (for me was and is

) then if he gets stuck or just don't want more you can show some good images to tell him that if he practices will be able to do that someday (When I see Caligari gallery it give me the wish to learn), if you see that he is evolving and can do some simple objects you could give him some funny goals.. I'm just uncertain about if you give him 7.x or 3.2

I really don't know, because 7.x is complicated but if he start learning it he could not pass through the adaptation process that I needed to pass...

So it's a difficult choice I'll give you the responsibility...
Hope you get good results, any question about my learning process just ask to me.
