a.)[3D] 
-using texture results in a slow scene (probably our fault)
-the gui/d3 tools exit with some SIGSEGV (again it may be us) 

b.)[net and gaming]
-Reversi, n-in-a-row
-'Rubicon-and-friends'-like games and morphing: full groups, plastic rendering, single-agent game (GUI), autosolver
-perhaps replace the thread-per-socket framework by a client-server architecture based on java.nio.*

c.)[engine]
-once in a while the Chess engine will refute to return a move but think forever, saving the reached end position and starting a new game from this point will have no problems though! 
(repair this, has it to do with search inconsistencies, the new start simply empties the hashtables)?! 
-experiment with more standard tricks

d.)[retrograde]

e.)[problems]
-create a nice Grimshaw problem

f.)[math]
-ExportData -q: creating and storing the trails/orbits for every constellation doesn't make sense, instead use a HashMap (which for a given starting position will return the result of applying the generator "a" or "aa" respectively)
-extend the 2-body system procedure to the case of general graphs with boundaries
-fillTrails: replace the use of face_ids (for the labels in sp) with pairs of point_ids (or edges) in order to be able to deal with faces-connected-over-multiple-edges
-try out alternative coordinate lines (for example on a rubik_cube_3) and observe the effects on the resulting group (should be none, or not?!) 
-translate the stuff about permutations into the world of modules to reach the next level of knowledge:-)
-generalize the holonomy group (that is to say: not only for a piece of type A)
-first of all find all possible graphs resulting from the morphing procedure, then later on deal with the group
-standard dynamics as in classical mechanics
-simplified explicit n-body forward simulation (some system of coupled diff. equ. animation)
-start the cellular automata topic (again just eye-candy is enough)

g.)[general]
-clean up, profile, tune and tweak the source code
