Programmer in Computer Museum Cartoon Scene

Create a 16:9 2D cartoon scene inside a computer museum. In the center of the exhibit hall, a programmer is demonstrating {argument name="programming language" default="C language"} programming while many visitors gather around and watch. The screen should show clearly readable {argument name="code type" default="C code"}. Beside the programmer, place a sign that reads: "{argument name="sign text" default="Ancient-Style Programming, Live Demo"}." Keep the composition playful, clean, and museum-like, with the programmer as the focal point.
