Yes. And Yes. The ones in the pic 65er posted are home made. Last I knew, there were instructions down in the Winter Cycling forum.
One caveat: While home brew work fantastically off-road and on roads covered with ice and hardpack (as they seem to be in Alberta), they're not so hot when they meet pavement. (Although according to my nephew, the sparks are impressive.) Likewise, commercial ones with steel studs also wear out quickly on pavement, and are better suited for off-road.
Stud placement is really important, key is to set them so that they are off camber and don't engage when you are riding in a straight line at normal psi but engage when you are turning... by doing that you don't wear out the studs and the tyres roll well. Drop the pressure a little and you will get steady engagement on icy roads.
For off road and snow, the biggest fattest mtb tyres you can find will give you maximum float and then you can can it a step farther... fatbikes are terrible on ice because of the low contact pressure on the tyres and really need studs.

More self studded... they are going into their 3rd winter. Note the second picture as it shows how the off camber studs do not make constant contact
