Nice project. I've messed around with cubes in the past. Curious what algorithm you used for the cube? I was mostly working with powersets and trees, and then experimented with dwarf petacubes. Do you have a limit on dimensions due to code, beyond what fits in memory?
No dimensionality limits but I wouldn't use this for truly high-dimensional problems like text analysis and inverted indexes (1000s of dimensions). It might work but I wasn't really thinking about those kinds of use cases when building this.
