Using the ideas of Sandy that were here about a month back, i have been working on a 5x5x5 extended --> 7x7x7.
i have completed a 2x2x5 (3x3x7) section of it, and have prepared all the other pieces. I should be done by tomorrow... Just waiting on my sticker order to arrive (ideal colors, from mark). I have also included pics of it, and the "extensors".
I am quite pleased with the current results, although i am dissapointed by the color. I had ordered them in black, but somewhere along the line, the order for pieces went wrong. I decided to continue though, no matter what the color. After stickering, it will probably look pretty cool with the shiny background.
