Psychedelic Live Wallpaper - Animated tie dye patterns. A swirling pop art kaleidoscope animated background.
This crazy trippy psychedelic live wallpaper is made in celebration of Grateful Dead fans who used it a lot in their art and the art of Rock of the 1960's (Sixties) and the 1970's (Seventies).

Hippies and the beat generation celebrated the culture of peace and love with tie-dyed t-shirts. Also Fractal design.

• Now supports HD for Samsung Galaxy S3, S4, HTC One and similar HD phones!
• Tie Dye is often associated with Marijuana use.

GuitarFlex is a virtual guitar app which lets you play the guitar on your phone or tablet. It doesn't mind if you are a beginner or not, GuitarFlex is flexible because:

- You can play in three modes: solo, arpeggio, strum
- You can configure the fretboard with the chords of your choice, allowing you to play as many different songs as you like.

Solo: play melodies an riffs touching directly at a [fret, string] position. Play polyphonic (if your device is multitouch).

Arpeggio and Strum: configure a set of chords (or use one of the bundled sets) and play string-by-string (arpeggio) or strum the chord (strum).

You can create and edit sets of chords (presets). Use the bundled chords, or create more chords using the included chord figures. Chord figures are

transportable; just as you would move your hand up and down the fretboard, keeping the same relative positions.

There is a custom chord editor for creating ANY chord you want.

Six different guitar sounds: acoustic, classical and electric; both picked or fingered.

Beautifully animated string vibration looks like a real string.

Sound is usually better if you use headphones, or an external device. Try it!

GuitarFlex includes a manual explaining the different modes and options.

Infimines is a new version of the classic game Minesweeper. In this version, the board is infinite, but mines can be eliminated leaving mine-free zones (and populated with flowers).

The goal of the game is to locate mines, flag them, and removing them by leaving them isolated. Points are obtained by eliminating mines, the bigger the number of mines in a group, the higher the score in points.

This free version incluyes ads, and doesnt let the user choose skill level (percentage of mines). See full version (Infimines) for more details.

*Screen orientation, phones and tablets
This game has been designed for both phones and tablets. In vertical orientation, phone version is played, and in horizontal orientation, tablet version.

This game includes a complete help, which I include here:

*How to play
Your task in this game is to remove mines, as many as you can.
There are infinite tiles. Tiles can be in revealed or unrevealed state. If revealed, you can see that there is not a mine (if there was a mine, you would lose the game)
Tiles can be flagged without being revealed.
To remove mines, they must be: 1) flagged and 2) surrounded by digging around a mine, or a group of mines.
Mines may appear in groups. To remove groups of mines, all mines from group must be flagged, and all non-mine tiles must be revealed.
Removed mines will eventually turn into flowers, if enough distance is left from mines.

*Touch modes
Touching a revealed tile does nothing, but if you drag it you will drag the view. Use this to navigate around.
Touching an unrevealed tile is mode-dependant:

*Flag
Puts a flag on the tile, marking it as a mine. If the tile was already flagged, removes the flag.

*Dig
Reveals the tile. If there was a mine under the tile, you will lose the game.

*Zoom
In this mode, you simply drag the view. Use this mode to move around without worrying about flagging or digging unwanted tiles.
Also, if you use the two-finger zoom/pinch gesture you can zoom out to see a wider view.

*Fast Flag+Dig
First touch flags the tile. Second touch reveals it. The only thing you can\'t do is unflag a tile (use Flag mode for that).

*Numbers
A number on a tile gives information about how many mines are around.
"Around" means the 8 tiles surrounding a given tile.
The number ranges from 1 to 8 and counts the number of mines present in the 8 tiles surrounding the tile with the considered number.
In many cases, you can safely tell if an unrevealed tile is a mine, or not, specially in easier levels, with a lower percentage of mines.
