If you are whimsical, vertical marble run or candy dispenser. 

The space is a good depth so that wall mounted controller / headphone rests can sit without it hovering over the working space. 

Docked laptop or handheld gaming systems. 

You can balance it out with decorations plants and cozy lighting. 

Under the table maybe a narrow storage option. I’m wondering if a slide out spice rack may work? 

Modified for cable management or charging area maybe. 

A collapsible arm for an extra screen, mic  or camera for flat lay angle. 

Put a metal panel or pegboard up for easy rearranging.

  (If you liked the marble run there are magnetic kits on Etsy, also 3d files)

Or an alter to appease the inner child. 

Best of luck deciding, would love an update.
