I made a 3d bitmap word for my dad for his birthday. This will show you how to make your own. The process isn’t difficult but there are a few things you can do to make it easier.
First, choose a word you want to make a 3d bitmap version of. Write it out the way you would like it to appear, using a big fat marker (of a color you can easily see through) on graph paper. Use a pencil to fill in the squares which will actually become the boxes. Count the squares; this is how many cubes you will need to create. Add squares here and there if you think there might be areas which will end up being not that sturdy.
This is all quicker than using a graphic program to make a bitmapped word.
Now that you know how many cubes to cut out, decide how big you want the finished product to be. Here is a cube template you should easily be able to resize to whatever you want. Keep in mind that only using 3 letters and a 1 inch cube my finished product was 34 inches wide.
I found it easiest to glue up columns first, then glue the columns together.
Gluing the columns together first allows a little dry time which makes the columns a little more sturdy when pressing into the rest of the sculpture.
The Finished Product
You may want to glue the finished product to a board. When I presented mine, I snuck it into my parents’ house and put this on the dining room table for extra wow effect.
