DHTML

Work In Progress
This is currently being worked on! Check back later for more information... hopefully.

Ouch!
The following article, DHTML, mentions a feature exclusive to certain versions of the client.
Specifically: This feature was removed almost immediately after 2007. (NewWindow)

DHTML was a feature, added sometime before 2007, which would let you create and display HTML documents during gameplay. These were separate windows that would open on the user's computer.

Usage

local HtmlService = game:service("HtmlService")

local htmlWindow = HtmlService:NewWindow()
htmlWindow.DocumentComplete:connect(function()
	htmlWindow:SetBody([==[
<table width="420" height="190" border="0">
	  <tr>
		<td width="490" bgcolor="#FFFFFF"><font color="#000000"></font>
			<div align="center">
				<p><font color="#000000"><b>Hello, World!</b></font></p>
				<p><font color="#000000">I am a DHTML window!</font></p>
			</div>
		</td>
	</tr>
</table>
]==])	
	htmlWindow:Show()
end)
htmlWindow:Navigate()

You would end up with something like this:
