Buying the parts to make a custom lego figure and assembling a random character from the spares which somehow works out, creating props and odd looking totems from other spares (including helmet pieces and a spare set of Darth Maul's horns) and finally, visualising a scene to set. I might expand on the custom Garry's Mod play set and Gordon Freeman figure I've ordered and see what fun and workable shit I can come up with. It's a simple creative outlet for me and I'm loving it.
And now I should stop looking at blue light after midnight like a dumbass and get some fucking sleep. I'll never learn.
