Just got back from EDC, and got time to make a couple of videos and a web page about my shirt, and how to make your own:

I hate you…
No really I AM FREAKING JEALOUS!!!
I need larger fonts now.
AHHHHHHHHHHH
AHHHHHHHHHHH
AHHHHHHHHHHH
You need to include me for next year…
@Darren_Hedlund include you next time, you mean you going to edc too?
@Marc_MERLIN Hell yeah, now less sleep for me and more coding for pixels.
@Darren_Hedlund you don’t have to code, you can steal all my code and be ahead 
In turn, I also “borrowed” a fair amount of the code I’m using (even if I also wrote reasonable amounts).
@Marc_MERLIN Well, I have been learning from the masters such as yourself. One cannot just leech and never innovate.
Haha, I’m no master, except at reusing other people’s code so that I don’t have to rewrite stuff that’s already been written by someone else
Nice work, I saw you there, I was wearing the LED top hat 
@Tim_Lukasik oh cool. Do you have pictures?
@Tim_Lukasik oh, that hat. Yes, of course I saw it, well done. I was able to get a good shot of it, and put in on my EDC blog post: http://marc.merlins.org/perso/clubbing/post_2018-05-18_Another-EDC-in-Las-Vegas.html
@Marc_MERLIN Looks like a whole lot of fun
@Darren_Hedlund that’s because it is I think it’s 300,000+ people now, and pretty much any kind of EDM you can fancy, for 12H a “night” 3 nights in a row. It’s a bit grueling, but hard to beat
wish i ran into you! i was on stage flipping in our costumes haha
