I did it!
What do you think about this?

Nice!

How big is it compared to a revenge and what did you use for the inner mechanism?

EXCELLENT JOB! Can you take a few pictures of the mechanism if it's okay? ~

Outstanding! Very nice appearance. The pieces look like they are perfectly aligned.

It looks like it is built from an Eastsheen 5x5x5. Is that correct? Would you care to share your secrets?

Wow, that is amazing. I'd like one of those. How does it hold together? What did you make it from? What kind of tiles/stickers (can't tell) did you use?

Their size you can see on new pictures with regular Rubik's Cube 3x3x3 and mini Cube 5x5x5

Looks very professional, I like it a lot! Did you employ the same methods as Tony Fisher's, or is your internal mechanism different from his? Just curious. It would be very interesting to see the insides.

Yeah, very professional. How many 4x4x4s did you need? And how in the world did you do it?

For 4x4x5 I'm used two 4x4x4,for 5x5x4 three cubes.

Nicely done.
How much time did it take? Do you plan to build some more?

Tony Fisher used the Eastsheen 4x4x4 and 5x5x5 cubes and applied prosthetics to the pieces, allowing for functional mechanisms. the drawback is that they tended to be of an unwiedly size.

Oleg's method involves resculpting interior pieces. I'm guessing he reused the interior spider with a little modification and reshaped the various tongues to fit together.

Well, at least that's the approach I would use. The biggest trick to making puzzles for others if you don't have a machine shop is to streamline the building process as much as possible and make it repeatable so that it doesn't take weeks to make one.

Yeah, I think you could make a good deal of $ if you could get a cheap 4x4x5 mold.
