Oh, all kinds of stuff. It just depends on what I need in the moment. I helped create the machinery for artificial tissue replication back in the day, and after I got involved with the PPDC, I made tons of stuff for Kaiju waste management. My favorite was the Milking Machine, which — okay, gross name, but here me out; it extracts particular poisonous chemicals from Kaiju so that we can properly identify and treat any illnesses caused by them. Super handy when a Kaiju's blood is generally super toxic.

Oh! And one time, I made a toaster that plays a jack-in-the-box theme. The closer the toast was to complete, the faster the song would go.
