What you need:Adobe Illustrator
(that's what I used at least. Corel and Inkscape would probably be fine too...)1/4" birch plywood
cut to 24" width by 12" high. I cut it on the table saw with help from Kyle. Thanks Kyle!Epilogue laser cutting machine
(60 watts)Jump Drive
(or dropbox would work fine)Wood Glue
Note: the laser cutting machine will hold a board up to 24"x18". I cut mine arbitrarily and didn't use the whole piece.
To make the mobile part:This is the tutorial
I am using to make the actual mobile part. You could laser the hoop or just use one from a sewing store.
