Hi
For this weekend's challenge I'm looking for a "Something for the weekend" mousetrap.
You can make it as simple or as complex as you like and you can choose to composite it from photographs, illustrate it, model it in 3D, or animate it. It's entirely up to you.
Anything goes as long as it meets the forum rules on decency, copyright etc.
Anyone and everyone is welcome to have a go - whether you are a complete beginner or a Photoshop expert.
There are no prizes apart from the chance to practice, show off, or bring a bit of humour and fun. Don't be shy, join in and have a go!
When posting back your edited images please use jpeg and downsize to 1200px on the long side.
To download the image below in jpeg format with ICC color profile (sRGB) and without the forum scaling artefacts , right click and then use Save Image As /Save Target As (or similar depending on your browser).
Have fun
Dave

My cats, PennyLane and Phantom, would take care of it...

Haha! Thanks, Trevor
13 likes!!! That is a SFTW record and then some. Way to go (as we say around these parts).

I had the same thought, but have not had a lot of time for the forum since Friday. I also found the perspective confusing. The floor's vanishing point is high and left...
...and the scene has a tiny front to back convergence. I'm sure Dave can tell us what the camera focal length was for the render, but I am guessing it was 'long'.
Hi Trevor
Camera lens is 50mm focal length but with the "film" aspect ratio of 2.5:2 rather than the usual 35mm 3:2.
The camera is 0.27m from the floor and the mouse hole is 2.27m along the floor from the camera. The skirting board is 16cm high.

One of the things I like about these weekend things is the chance to get familiar with tools I don't often use. In this case, my experimentation didn't happen until after I had posted.
I wasn't really that happy with the image I posted, partly because the perspective looked off, but mostly because I realized seven-eighths of the way through that I had Resampling set to Nearest Neighbor, so I decided to try again.The train is something I found via Google, It's hard to find pictures of steam trains from an elevated viewpoint. I tried to match the perspective using Photoshop's perspective tools.
First I used Vanishing Point to etablish a Ground Plane:
To get a better idea of the perspective planes, I dragged up the sides:
I then made the "cage" a size to hold the train:
I then tried using Perspective Warp to match the train to the cage, but it changed the shape of the rail cars: making them narrow, or tilting the roofs to one side.
If I had Dave's expertise with Blender, I suppose I could have made my own train with proper perspective, but so far, my experience with blender has been limited to downloading it and buying a book

Hi
Some great images this week and cats seem to be a popular form of mousetrap 
Graham - thanks for starting us off. That's one creepy lady !
Rista - great take on the "mouse" theme.
Rafael - It may be a while before we see the mouse with those two patiently waiting outside.
Lesley - I love the expressions on teh cat and mouse - excellent!
Jacob - I like the cat hiding in the vase - clever cat! Terminator mouse sounds scary
Joan - Nice graphic.
Semaphoric - clever mouse , sort of Casey Jones of the mouse world.
Michael - Super mouse (or bat) - just showing teh shadow of the cat works well.
Dean - I see the electronic trap using the previous SFTW transistors ! Then in your second image the mouse looking through the top two holes must be huge, which explains the third image
Hothwampa - clever, particulraly with the flags for the "moose" and "moose".
Keep them coming - the SFTW weekend lasts until Thursday !
