I'm a lot more brash online. More modest in reality. I'm quite a calm person generally.
I don't take things seriously IRL because of my philosophy on life (family and health are the most important things) so on the Internet I am more prone to wasting time and getting lost in creative and playful pursuits just because I can. If I'm not at work or studying, I'm trying out something new like an animation idea or a game concept.
Someone once described my never ending uh, "impractical productivity" as an "IcyGamma way of doing things". For example, once on a CityRPG I setup a fake realty company website and made a page selling an apartment complex I had build; someone said that they wouldn't have bothered and what I had done "screamed of IcyGammaness" lol.
