At Amazon in the new Day 1 building their main staircase to the lobby is built from wood ends and it is done very nicely. It looks great. There's probably pictures online of that.
edit, I found one picture from a geekwire article. Unfortunately you can't see the grain, the picture is from a far. https://cdn.geekwire.com/wp-content/uploads/2016/11/20161107...
That is done because wood is soft and if you drop a tool or part on the floor it's far less likely to be damaged. Wood has been superseded by (usually vinyl IIRC) tile and/or rubber/plastic mats in a lot of places.

Looks like it's good for outside flooring. Actually doesn't look that bad when used for that either, kind of like bricks.

Each block is 6"x6" (15cm x 15cm) of pine. Apparently it lasts a long time, but took a long time to install.
