Big Bro Working Hard

Big Bro completing the binomial cube, one of his favorite works at the moment.
Using skittles...trying to come up with an extension of his own, after he had already correctly completed this work...
Here is his pink tower / brown stairs extension, after correctly doing the pink Tower and Brown Stairs work.

Big Bro has mostly been focusing on making his world biomes book...will post photos of his completed book soon.

These are just some of the other works he has been doing in addition to the biomes...
