Stacey,
The rotation task is specifically designed to do rotations of 2d
Polygons. You can specify the polygons manually (there are a couple
there used by default), but it really is not capable of representing or
projecting 3D objects. I think Shephard's original 3D tetrahedron
stimuli are available, as are more modern renderings. But these are
just images, and you would have to write a special-purpose 'player' to
show these images and collect responses. I have looked into this, but
as far as I could tell, the images were copyrighted, so there was no
point in a free testing software that relied on non-free stimuli to
work. I also once looked into doing a simple 3D projection, but my
geometry skills failed me and I couldn't make it work.
I should note that the current version has been used in several
published papers that establish their reliability and validity:

There are also other rotation tasks you might look at; the matrix
rotation task, one using attneave shapes (see herehttp://obereed.net/do
cs/Mueller2010.pdf )
With respect to tower of hanoi, these problems are randomly generated,
but there is another set (if you change the problemset to "bishop"
originally published by Bishop et al (2001), although that was probably
intended for children. I know there are a few other normed problem sets
out there, but I haven't taken the time to track them down and
implement them. If you want to implement another set, you need to edit
the code at the bottom of the TOH.pbl file to specify the start/end and
minimum moves. Each line bolow specifies the starting configuration,
the end configuration, start/end labels (I think this is just for data
recording), and the minimum number of moves needed. I think the
position code specifies which pole each disk starts on, from largest to
smallest disk probably.
probs <- [[[1,1], [3,3], 11, 33,
3], [[1,2,2],[3,3,3],122,333,4], [[1,1,1],[3,2,
2],111,322,4], [[1,2,3],[3,3,3],123,333,5],
[[1,1,1],[3,2,1],111,321,5], [[1,1,3],[3,3,3],113,
333,6], [[1,1,1],[3,3,1],111,331,6], [[
1,1,1],[3,3,3],111,333,7], [[1,1,1],[2,1,1],111,211,7],
[[2,1,1,1],[3,3,3,3],2111,3333,8],
[[1,1,1,1],[2,3,3,3],1111,2333,8], [[2,1,1,3],[3,3
,3,3],2113,3333,9], [[1,1,1,1],[2,3,3,1],1111,
2331,9] ]
If these problems are not good and you have another set, let me know
and I'll see about adding them to the battery.
