The cake may have been a lie, but the cube is real. Do you miss your cube and can't wait for Portal 2? If so, then why not make your very own companion. And there's no need to throw this one in the incinerator.
An intermediate knowledge of knitting, you will need to be able to increase, decrease, cast on at the beginning of a row, pick up stitches and to knit intarsia or embroider over stitches to look like intarsia. A basic knowledge of how cubes are constructed is also useful.
Dark Grey –about 300g 12ply acrylic (I had to buy 2 x 200g balls, but I didn't use a lot from the second ball)
Light Grey – about 400g
Pink – small amount (I didn't actually have pink in 12 ply, so I used 2 strands of 8ply for the pink)
Stuffing material, I used a bit over 1kg of polyfill.
Using 12 ply yarn and 5mm needles, the finished cube is about 45cm across. You could use 8ply yarn and smaller needles (3mm maybe) and the result will be smaller and will probably use less yarn, but I haven’t had a chance to see the results yet.
At the time of writing this, I have a smaller cube close to being finished. Using 8 ply yarn and 3.25mm needles, the cube looks like it will be about 25cm across and has used 1 x 100g ball of dark grey.
St st – Stocking stitch

All instructions to increase and decrease mean increase or decrease 1 stitch in either first stitch (beginning of row) or last stitch (end of row)
All pieces are worked in stocking stitch throughout.
Numbers in brackets at the end of instructions refer to the number of stitches you should have after finishing that row.
