### Solutions for Act IV Scene 1 - Sketchy

There's a lot going on on this puzzle, so let's try and figure what everything actually is. It appears we have 3 important sets of objects. Dots, cameras, and skateboards.

The first thing to notice is that there seems to be a relationship between the dots and cameras, since for every coloured dot in a diagram there is at least one camera looking towards it of the same colour. (A camera's colour being determined by the colour of the "REC" in the corner.) The natural conclusion to make here is that only cameras of the same colour as a dot can see it. Further the orientation of the REC in each frame seems to suggest the orientation that each camera is sitting at.

So we have a a small understanding of the cameras and dots, but what about the skateboards? We are provided with feet and arrows to suggest in which direction they move. There seems to only be three feet/arrow combinations, and a quick bit of research will reveal that they are representing the feet movements required to perform three tricks, namely, a kickflip, heelflip, and shuvit.

The leap here is to realise that if we view the dots in a plane attached to the top of the skateboard, so they move around with the skateboard as it performs each trick, we can Sketch out the paths of each dot as viewed from each corresponding camera.

In the top left corner, for example, the trick being performed is a kickflip. So as seen from the orange camera, the orange dot will sweep out an entire orange circle as the board flips around completely. The red dot will simply sketch a straight vertical line when viewed from the top camera (since in a kickflip the board rises off the ground in order to flip), and a horizontal line when viewed from the side camera. If drawn carefully, these two lines join together to make a red T shape. Finally, we have the grey dot which makes a horizontal line by moving to the left and then right of the camera frame.

This can be done for all the skateboards in our grid, and it turns out that all coloured dots (except the red) sketch out shapes, specifically orange circles or pink squares, and our grey dots move in vertical or horizontal lines. Omitting the red letters, we have the following:

 C + LR C + LR C + LR C + UD C + UD Sq + L C + LR Sq + L Sq + L C + LR C + UD C + UD

Since the grey dots make lines instead of shapes, the above notation represents the order in which the lines are made (i.e. LR = Left then Right).

Finally, the red letters that we retrieved from the first column are "THPS", which is referring to the well known skateboarding game "Tony Hawk's Pro Skater". Note that all circles are orange, squares are pink, and lines are grey, and these same colours are also seen on the circle, square and arrow keys of a Playstation controller.

The leap here is to realise that the shapes and directions we have are actually giving us instructions to perform tricks in the original THPS game for Playstation. A list of tricks and their point values can be found here. Our grid now looks like this:

 Fingerflip Airwalk Fingerflip Airwalk Fingerflip Airwalk Backflip Backflip Kickflip Fingerflip Airwalk Kickflip Kickflip Fingerflip Airwalk Backflip Backflip

We still somehow need to retrieve a word or phrase from all of this, and the only thing we have not used is the logos present on each skateboard. The only thing these tricks have in common is that their point values in the game above have a value of either 100, 2000 or 4000, and the final leap here is to realise that we can index the names of the respective skateboard companies on each board by either taking the 1st, 2nd or 4th letter, depending on the score of the trick in that diagram.

 2000 + Etnies = T 2000 + Converse = O 2000 + Enjoi = N 4000 + ZooYork = Y 4000 + Plan B = N 100 + Independent = I 2000 + DC Shoes = C 100 + KR3W = K 100 + Nike SB = N 2000 + Fallen = A 4000 + Element = M 4000 + New Era = E

Reading left to right, top to bottom gives the phrase "TONYNICKNAME", suggesting that the answer should be the well known nickname for Tony Hawk AKA "The Birdman".

Design Notes:
In a few of the tricks, the 2 grey lines could possibly be interpreted as RL instead of LR, or UD instead of DU, but we hoped that the mechanic would eventually ensure that puzzlers took the correct ordering (since regardless of UD or DU you get a trick with the same 4000 point score, and there are no RL + tricks with a circle nor with a flat thousand/hundred score.)
