"Heya, just wanted to say that's a pretty sweet hack. Not gonna work on the latest Gmod updates though, but it's always good to see some old-school creativity. You got the source code available?"
"Lol, nice one, simple and clean is always best, but don't expect this to fly under the radar, Gmod dev's are always on the lookout for cheaters. I'd imagine this would work for a while till they update the client, but kudos for creating it. Anyone know if it'll work with the new update?"
"Hey, I think I can help you out here. I used to mess around with Gmod scripts back in the day and I think this 'draw' or 'gui' library can help you achieve some sweet visuals without touching the game's core mechanics. Anyone else have experience with these libraries?"
"Lol nice hack, I remember seeing some of these mods back in the day. Can you share the script, I'm curious about the visual effects you mentioned. Does it work on the latest Gmod version?"
