I'm sure that most of you saw it straight away, but it had me fooled until after I'd finished it. It is a compound of ten cubes, but I was convinced at first that it was a compound of only five - until I twigged that there were some corners missing. The ten cubes are aligned with the five incomplete cubes that I thought I was seeing.
I stumbled upon this when playing "the stellation game" with Stella, with a triacontahedron as base. I don't know how long I'd been clicking at this point, but I think it was about 20 or 30 stellations in.
Hope you like it. It looks very good next to a compound of five tetrahedra in the same colours.
This polyhedron is one of 5 that I intend to make.
Its tetrahedral equivalent is a stellation of the regular dodecahedron. I made it last year.
Its octahedral and cubic equivalents are both stellations of the pentagonal icositetrahedron. I made both a year or two ago.
Its icosahedral equivalent is a stellation of the pentagonal hexecontahedron. No doubt it will be a pain to make. I'm not sure whether it can be made using 5 colours.
This one is a stellation of the rhombic triacontahedron - I'm going to make it using 15 colours.
