Nick Furry's projector device holograms

Peter gets a surprise visit from Nick Fury - which is usually not a positive visit. The design of Fury's holograms had to be tactical, slick spy gear.  When Nick Fury tracks down Peter in Italy, he uses a portable hologram projector to illustrate the global scale of the impending danger. The design of Fury's holograms had to be tactical, super cool with a military kick. Point clouds and lidar scan-like visuals were used to communicate the complexity and real-time nature of the data.

Mysterio's helmet HUD

Beck's Helmet is his battlefield view into the simulations - his master console.  Everything is built to serve the illusion and to give Beck the most control in the field.

Combined with the wrist device, he has on-the-fly control over the course of the illusion's timeline, adapting to unforeseen situations as needed. He can revise the story using pre-built actions and live-record any new actions he wants. The helmet also gives Beck the ability to communicate both as Mysterio and Beck to various parties, including Nick Fury and his own team as he orchestrates the chaos.
