I think gears should just be geometry now. Pulleys could use chains like the gate demo.

Option for text, add these two functions to my imgui_user.xxx

void ScreenText( const ImVec2& Pos, ImU32 Col, const char* Format, ... )
    {
    va_list Args;
    va_start( Args, Format );
    ScreenTextV( Pos, Col, Format, Args );
    va_end( Args );
    }

void ScreenTextV( const ImVec2& Pos, ImU32 Col, const char* Format, va_list Args )
    {
    char Text[ 512 ];
    vsprintf_s( Text, Format, Args );

    ImGuiViewport* Viewport = ImGui::GetMainViewport();
    ImDrawList* DrawList = ImGui::GetBackgroundDrawList( Viewport );
    DrawList->AddText( IMGUI_FONT_REGULAR_BOLD, 0.0f, Viewport->WorkPos + Pos, Col, Text );
    }
