Garage object

Power for things that move.

A closing garage scene for the portfolio: generation, ignition, and small systems that turn ideas into motion. Move the cursor and the parts respond quietly in the background.

alternator / converts motion into electrical output. a small symbol for systems that keep moving after launch.

lighter / ignition object. the first spark before a product becomes real.

Portfolio museum

Walk through the projects.

A small third-person room where each artwork acts like a project exhibit. Move close to inspect the work.

Walk close to an artwork to inspect it.

Delivery system

Systems delivered, not just displayed.

A small trolley moves the packed ideas across the floor: project files, interfaces, and experiments arriving as one system.

Take the receipt on the way out.

The final counter turns the visit into a small checkout slip, like buying a print from the museum shop.
